That's an easy repair, 3-4 hours labor, overhaul the rear cover, and they will paint to match. Plastic covers are repaired all the time, even with alot more damage than that. Any good shop will take good care of you for waaay less than replacement cost. I've even seen a bumper completely torn into and glued/plastic welded back together w/ a special epoxy just to prove a point. It can be done and the repaired part was stronger than the rest of the bumper. Shops will tell you it needs to be replaced because they make mark up on the part.
Also, as for the paint match, any good shop will match it just fine, but that's all the more reason the repair it vs. replaceing it.
Lastly, anytime you buy a new part aftermarket, oem, or remanufacured, you run the risk of the holes not matching up just right which means a crappy fit. Since you know your cover fits just find a good shop that will hook you up! Good luck!!
