Contractor Recommendation - Construction of Soundproof Entertainment Room

I am seeking a contractor who is knowledgeable about and can undertake the construction of a soundproof entertainment room. The room at issue is a separate living suite in our home but the main area in the room needs to be soundproofed so that it can be used as an entertainment room.

Any recommendations would be appreciated.

Thanks.

Didn?t the guy from Broadcom have one of those?

I don't know any installers, but I think the best way to go about this is to find home theater installers, they should know how to soundproof the walls/ceiling etc., build the ceilings and walls for best soundstaging, speaker placement, figuring out lighting for different types of entertainment, throwing a party for a game vs watching a movie.  I assume this will all be done since you're pulling down the drywall for the soundproofing.  I'd put in wall/ceiling speakers, subs, as well as running all the wires you potentially need to your projector and TV from the entertainment rack. 

I'd go to avsforums for more information and referrals, hardcore enthusiasts over on that forum.
