Yellow pages, man. I found a guy here in Omaha that will do some work pretty cheap. Best thing to do is just look around in your local area, and price match. It takes little time an patience but its well worth it.
I've been saying for the last 6 years, that someone here needs to get a good set-up from Caswell Plating and become the official board "plater", but so far no one's rose to the occasion. Heh, they'd be rich about 5 minutes later...
