I live near a large enough City that finding a plating shop that would run my stuff was not a problem. I had to wait until they had a full load, but time was not an issue for me. I would agree with Regis that it doesn't pay to try and do it small scale, sporadic production on your own. Let someone else worry about EPA, carry the inventory and the overhead involved. The only other thing I would add is to be sure that your parts surface quality is what you want. hand finish your brass parts before you send it out. Plating is only a couple thou thick and imperfections will not get totally covered up.
