I have a contact in one of the major pool leagues in Newmark, and I've sent them a message asking for any recommendations on pool table installations. I'll definitely post the info as soon as I get a response.
Until then, you may want to start calling around to the various suppliers in your area. Here is a list to get you started. Really though, hold off on deciding until you get my reply. A personal recommendation is the best decision making tool for this stuff in my mind.
