Should I expect a discount from dealer for buying and installing complete system

I really appreciate the comments. I am really getting a tremendous amount of useful information. I had never thought about a service agreement. That's a great idea.
I don't think that around $3000 is a lot for the amount of work that needs to be done. The owner has been to my house and understands the work involved. As I have said my home theater was installed when my room was just frame and all the wiring is behind the walls. 
I have checked the price on everything except the HDMI cable which I need to check as it seems expensive. Everything that I have checked is list price. I could do better I guess if I bought everything on Ebay or if I looked on Craig's list but thats not what I want to do. 
I get a lot of criticism for choosing Sony and I pretty much know that people just have an attitude without hearing it. I was pretty much shocked when I found out that this business was selling Sony. As I have said they are extremely high end and have always sold Anthem. I have read all the reviews that I can find and they are almost all positive. I read the 
Stereophile review which was a bit negative but it was written I think in 2014 or 2015 and so its not reviewing the current model. If you read customer reviews, most people are happy. I have heard Anthem which is great and I have heard Sony which was great. If my dealer who I trust says I will be better off with Sony, I will take his advice. It's not as though he is making more money on Sony. He could easily suggest the 1120 Anthem which I would have bought but he strongly suggested Sony and not even the top model. I decide to spend the extra $500 for the top of the line even though he said I don't need it with the 75F speakers.
Before I make my final decision though on the Sony I will have him play me again the 720 Anthem and have him explain exactly why the Sony would be better. I think though that I would be looking at the 1120 as the 720 only has 7 amps and I would need to buy additional amps to cover 5.1.4 and my bedroom. 
I will definitely ask for 15% discount on equipment when I am done deciding on what I want to buy.
Yesterday I pretty much decided I want to add a Bluesound music streamer and I have to decide which model. 
I think I have explained that its as though I can make an offer and if does not accept then walk away. This business is the best by far in my area. My alternatives would be Magnolia, or to buy from a home theater installer. As I have said, he is not jacking up the prices on the equipment. They are list prices that are the same everywhere and I totally trust that they will do an excellent job with the install. I will ask for a package deal that would include a service agreement, I will ask for 15% off of the equipment but I won't be going elsewhere. The owner has been to my house, I have been to the store numerous times, asking questions taking up their time, and having them audition the equipment. 
It's hard to answer every comment so I have tried to be comprehensive in my comments.
I like the idea of asking 15% and having him counter. I will ask for service agreement. I won't walk away if I don't get the 15%. I do believe that this business is completely honest and ethical and they are not out to get my last dollar. I do trust their opinions on which brands to buy but I make my own decisions. For instance my dealer downsells me. He suggested a lower level Paradigm floor speaker and center speaker but I decide to go with the higher priced 75F and the 55C. He suggested the mid priced Sony and I wanted the more expensive 9 channel. If after hearing the Anthem again, if I feel that it is a better buy than Sony I will choose it

Or it could be the dealer has a higher profit margin in the Sony. It’s very possible.
By all means I would listen to both HT receivers again. Call the dealer and ask him if he has the Blu-Ray movie, first release, "John Wick". The sound track is recorded in, "English Dolby TrueHD Atmos Mix". If not you should buy a copy and take it with you.

The $125.00 an hour for qualified audio technician or electrician is what I would expect to pay for one person where I live. The helper should be 1/2 of that in my area.  The rate of $250.00 and hour for two men, could be a competitive rate in a major NE metropolitan city?

It’s been a while since I messed with home theatre in a serious way, but the last big one had lots of complications in terms of pulling cable, getting it all working- lots of gear racked up on big custom made Mid Atlantic racks- my electrician at the time came to install power outlets for the projector,  and a 240 volt line to feed a separate power system for the thing, but the install team worked very hard, long days, and I’m glad I was capped out at a flat rate for the whole package. The end product was great- but it took time. So, I didn’t really quibble about the line items of equipment cost- some of it was stuff I already owned that was refurbished- (I was insane enough to be running 3 ARC tube amps for the midrange at the time) plus woofers, plus all kinds of other stuff that, today, would probably be built in -native rate scaler/video switcher- etc.
It was not an easy install. The room was not to the studs, it was a finished room that required a lot of hole punching to pull cable.
The finished system was great- the owner of the company drove up from the city to see it and make sure I was satisfied. And apart from a few changes I made myself over time- eventually disconnecting the tube amps in favor of solid state --it just got too hot-- I don’t remember haven’t any issue with that set up, which was done in around 2005? and ran until I moved in around 2017. (I had upgraded the projector and a few other things over time which required follow up visits but nothing drastic).
The biggest issue to me was making sure it was done right, done well, and was reliable, and that there was support. That’s worth the little extra the guy might make by not discounting the equipment. Have you seen any of his other installs? And apart from the equipment warranties, what ’warranty’ do you get if things go awry and you need a visit to readjust, tweak settings or deal with some problem?
I’m sure modern home theatre can be less complex now (I use a small system that I basically installed myself- no more projection and huge theatre like experience). But, the key to me is getting it done cleanly and having the support if something goes down.

If the dealer is making a larger profit on Sony then why would one salesman and both of the two co-owners suggested the 7amp version rather than the 9 amp version which is $500 more. I really think people don't get that this is is not an operation like Magnolia. https://www.musicloversaudio.com
They are not trying to suck every dollar from me, it's the opposite.
Yes, I agree about having it done right. This business will do it right, I have no doubt.
Like I have said this isn't a simple installation as every wire including the sub is hidden in the walls as the room was just a frame when my 5.1 system was installed. All the electronics are in a closet so it will be a lot of work to do the wiring.
The owner loves the John Wick movie and he demoed the Atmos with the DVD. Was great with my speakers and the 7 amp Sony receiver with the 45C center so I know it will sound even better with the more powerful receiver and the 55C center
