You'll get some enthusiastic response to this at the Pronto forum. Custom installation firms often discourage moonlighting so you would be better off trying to get the support of an amateur at the Pronto forum or contacting a good custom installation firm via phone. You can get the address and phone number of a reputable firm from the website www.cedia.org just click on the help for homeowners and type in your zip code.

Best Regards,
