Hey Mike, look up "jonyb" here on OSO. He's not active here much, but his business is doing well; and is in your region.

He's taken great care of a couple friends and members here. His advice is sound, and can supply according to your needs.
He had the exact same boat as a local buddy of mine, and sent him and entire stereo system with wire lengths pre-cut and labelled, the works.
