Ideal Manufacturers for your local hi-fi shop...?

I'm a college student, and am majoring in Business and Econ/Finance to one day open up an audio shop. I want to focus on multi-channel music reproduction and true high fidelity home theater; something worth listening to music on.

This coming semester I will be in an Entrepreneurship (Small Business Management) class and have to create a fictional business, my choice as to what business seems obvious.

I’ve chosen a few manufacturers that I believe offer a good balance to and selection for a variety of price ranges. This will be a mostly audio based store, so keep that in mind. I would like feedback from the experts/obsessed, like myself, as to what vendor you would recommend adding or omitting to this list. Please keep in mind a couple of things though. 1. This is not a list of my favorite manufacturers; the goal is a list of an ideal selection. 2. The list will ideally be as short as possible as I will just starting out and will make life and the project easier. 3. Any advice on how to get vendors to sell at a brand new store (under real life circumstances) would be greatly appreciated. 4. The goal is high end home theater and multi-channel music reproduction, but we all know 2 channel can’t be ignored.

Parasound Halo (very attractive products, a good 2 channel preamp, the JC-1 bargain “A” rated bargain monoblocks)
Rotel (the only “receiver” offered for those wanting a smaller system, as well as a more affordable home theater alternative with there cheaper pre/pros, they also offer a universal disc player)
Meridian (The cutting edge in digital sources and pre/pros, the G series would be a very attractive option for most customers, hopefully.. No desire to sell their speakers if possible)
PS Audio (A wide range of power products, but not as generic as the Monster brand I would not sell their audio cables if possible)
Audioquest (Once again we have a single company with a solid background and a wide range of product. They also appear to me to be a good value)
Mark Levinson (All the amplification I could want, as well as the best 2 channel pres and cd players I would offer)
Revel (For a class A rated speaker the Ultima Studio is a bargain and offers full range in both frequency and dynamics, they also offer a worthy center, the most important channel, and surrounds. Their new SUB30 is supposed to be great as well.)
Totem Acoustic (This would be my average speaker, they offer a traditional look with wood grains versus the modern Revels, they also are dynamic yet small to be room friend [waf] They Their price range would dip to the bottom end, with the rainmaker or Dreamcatcher paired with a rotel receiver)
Gallo Acoustic (Once again we have a bargain buy with the Reference 3, but also another worthy center, the Duo. They also offer a great alternative to in-walls for those with picky decors.

I want each and every comment from all that took the time to read this entire thread, sorry so long, and thanks a ton for the help.
