There are loads of places that claim to do this, but often all they'll do is clean the wheel up a bit and spray it with ordinary paint. This will not last, you get what you pay for.
Have a look at these guys:

IMHO they are the best in the UK and not exceptionally expensive. I know they are nowhere near you, but give them a ring as they operate a UK-wide collection and delivery service.
They pretty much replicate the manufaturer's process, by stripping the wheel completely, blasting it clean, repairing any damage, powder coat and bake the new finish, re-fit and balance tyres etc.
I had a wheel done on my Jag. It had previously been done by one of the "cheap" places, and after less than a year it was bubbling up with corrosion and the laquer peeling off. I got S&P to do it and it came back as good as the original factory finish. No, actually that's not true, it was better than original, the paint was thicker and smoother, and 7 years later it's still immaculate and totally undamaged.
BTW when I say "repair any damage" they can resurrect some pretty badly damaged wheels, including bent ones and ones with lumps knocked out - and they don't just wodge a load of filler in there....
I don't have any connection with this company, just a very impressed and happy client.
Cheers
