Chuck, the problem I see with having someone do that for you is.....
1. To properly prep a bolt for plating it ch irst needs to be inspected for corrosion, stripped/crossed threads, wrench marks and proper function of any integral/captured washers.
2. Any above issues need to be addresses before plating or you have wasted time, money and otherwise usable bolts.

Of all the hundreds of thousands of bolts I have played it over the years the only way to really do it properly is to inspect and dress and tap each bolt individually. And to pay someone to do that can be exorbitant.
