Rear end accident. Need tailgate replaced. Glass is still usable. Rear bumper needs to be replaced. No structural damage to car.

What is your question?

The rear end was in an accident and my tailgate got a blow on the left hand side and the rear bumper on the left hand side was also impacted. No lights were affected and no signs of structural damage. Have not opened up the tailgate due to not knowing if it will close or not so there may be a possibility that the locking mechanism may* need to be replaced once the tailgate is opened and checked to see if it locks. Need to know how much the ballpark cost range may be for this job and the parts cost. Also, where to look for parts.
