These guys work out of a unit a few down from mine:http://www.pacificcoastpowdercoating.net/
They do quick, excellent, and fair priced work. Ask for Kevin or Brandon and tell say Uri from ColorRite sent you. They even run to LA all the time so they'll be able to help arrange pick-up or drop-off.
I'm not affiliated with them in any way, BTW, they are just good people.
