Just do it yourself. Rub it back, file down the high spots, bit of chemical metal in the low spots, contact the wheel manufacturer and get a paint code and touch it up. After its touched up flat it back with some 3000 grit detailing paper then repolish the whole wheel. Easy peasy, cost no more than a tenner. I cant see the point in paying hundreds to make it perfect again, its only going to get kerbed again.
