I'm not sure that any bike repair shop or even frame builder would touch the fork. In my experience, they're all petrified at working on such an obvious issue. That's especially true considering the litigious environment that any shop or builder has to contend with in doing any sort of business. If they repair it and it subsequently fails, injuring the rider, it "might" just end their career with an embarrassing lawsuit. I've taken a fork that had equally serious issues and not one shop or frame builder would even touch it.

All that to say, don't expect a shop to be eager to do the work.
