Hi End Audio Technician in Las Vegas

I have a sound system  that was installed in my house about 15 years ago, needless to say; it need upgrades, etc. the system incudes: Theta Casablanca 3, Casablanca amps (2), Induction Dynamics speakers (7) etc. I live in Las Vegas NV. and I'm having problems finding somebody that is knowledgeable of this type of technology and I don't know enough to do it my self!  Does anyone know somebody in Las Vegas or know how to find somebody  that can deal with this type of system? Thank you in advance!!
All the equipment is in one closet with lots of wires going behind the walls to the tv/ music room, and that’s part if the problem, finding someone that knows how to identify every connection!!i had some different guys , including Best Buy and some higher end companies and they think it a little to complicated for them!
I know a guy, let me check with him. He doesn't like to deal with in wall speakers, but wiring should be no problem. Hi end company? They should be able to handle it without a problem, BestBuy NO. Any idea of time frame?
