I was in the same situation of having ALL my rims bent by a darn road construction and the contractor would not admit the fault. I was of course very frustrated and looked at approx. $1200 replacement cost out of my pocket for the rims...
WheelBenderMender.com was an inexpensive solution for about $490 to get ALL 4 bent wheels fixed. Check them out.
