So I finally got a hold of Millers and they quoted me $75/wheel. They said they do not actually do repair, but stated that they do smooth out most rough edges in their sanding process, before powdercoating. And they also do not mount/unmount.
I also spoke to Alloy Wheel Repair Specialist and they quoted me $150/wheel for repair and paint. This was the mobile guy behind Mercedes-Benz of Buckhead.
