The EPA has made decorative chrome incredibly expensive as a process and most platers have simply stopped offering. If you find someone willing to take your work, you might be stuck with whatever pricing they charge. If they're pricing is based on a lot charge, maybe you can find some other folks that need some plating of their own and can help you get your money's worth. We used to have stuff occasionally plated for cut away models and display pieces here at work. These days we have that sort of thing nickel plated instead of chromed. It isn't as reflective as chrome, but it still looks pretty good IMHO.
