For Powder Coating of wheels (in the south at least) try Swanick Gritblast not too far from Southampton, they did the centres on my RM's and made a beautiful job, i think I paid £100, that was for the wheels to be stripped and the centres and inner ring to be powder coated and the centre nut to be painted in 2 pack, all done within a week. They also did a friends 18" wheels for his focus, he told them he needed them very quickly, and true to their word the job was done in 2 1/2 days... very good service indeed
