Depending on where you live, you can send them to a repair shop that specialises in rim repair. I live in Ottawa, Canada and I have to send my rims to Montreal which is like 2 hours away to get them repaired. I called to get a price quote from them and they were approximately as follows, these are in Cdn prices; $65+, if just straightening rim, $100+ if straigtening and it cracks so they have to weld it, $100+ if straigtening, weld and polishing.
these were just rough quotes but we will see as I have to get 3 rims straigtened!
