Need Acoustic Design Help in Scottsdale Az

I am looking for recommendations for a local company that does acoustical recommendation for Post Construction. Two Channel room with two full range speakers.

I have a simple 10x12 room with a closet wall protruding into the room 2 feet, with carpet floors and one window. Really a simple room but I want to get it right the first time and not have to buy more treatment than necessary.

I have talked with Rives and I am still considering his services but would prefer to find someone local who has some clients local that I might be able to survey his work.

Thanks
Chris
