Well its not too hard to do it DIY, just VERY time consuming! just done a friends wheel for him but took a long time (did the whole wheel, including removing curbing) looked great though! about a week after a car drove into his while parked and curbed the others. The garage did the others but couldn't believe the one i did was a diy job!
