Hmm, that's a bit more than I was expecting for a small repair. I had my ZHP wheels completely refinished by Detroit Vintage Wheels in Royal Oak and they did it for $150 per wheel. (Initially I was quoted $200 per wheel but that price is for if you wanted to ship and have them shipped back.)
For that price the wheels were media blasted to bare alloy, welded to fill some deep gouges on the spokes and then powder coated. I'll post some pics later when I get a chance to take some but I was quite happy with the job they did.
