Need shop to oil rub bronze my chrome fixtures

+++++++

I am looking to find a plater/coater to put a oil rubbed bronze finish on some plumbing hardware(two single valve handle shower faucets and two towel bars for a shower door).
We are building a new home and the plumbing valves for our shower stalls have been installed, walls plastered and painted. Unfortunately we have changed our mind about going with chrome and now want oil rubbed bronze (a finish the valve manufacturer does not make).
Rather than putting large holes in the wall to replace the valve we are looking to refinish the trim/handle for the shower faucet.
