If you're at all mechanically inclined, you could try straightening them yourself. The idea is to exactly reverse the forces that got them bent. You have to improvise with tools you have at hand, but a press or hydraulic jack can do the job. You need to clamp the steerer tube right above the fork crown, mimicking the support of the crown bearing, and apply force directly to the dropouts. Try with moderate force, check for reduction of the bend, and, iteratively, apply gradually increasing force until it is straight.
