Any Consultation available to set up a system with used equipment

which city?

it sounds like you are in a dangerous situation where you may end up spending a lot of money for little value. I would decide if home theater or 2 channel were my priority and focus on one. 

sounds like you have a budget to work with a dealer/professional audio installer. For this much money, you can buy new too. The benefit is the return policy, for 30-60 days you can return it no questions asked, You can see a lot of speakers here  https://speakerchoices.com/

but I sure don’t have the confidence to make any suggestions for you in your price range.
