Hi Boston, ever considered outsourcing out of America ? I'm in Malaysia & I have a friend who is able to chrome-plate nylons over here. His company happens to be the 1st choice of chrome-plating plastics in Malaysia, with MNC customers (even American) in the electronics & automotive industries. Small or big parts are not a problem, as his facility caters to power buttons for stereo sets right up to radiator grilles for cars.
Doing this process in Malaysia will actually cost you a lot less in the long run. Think about it.
Contact me if you are interested for more details.
