How to pin front grill back in place or cost for garage to repair

What is your question?

Bought used car for daughter, car fax said previous owner had minor accident, something about hitting a garage door, we have had the car for 9 months and front grill is now sagging out of place. I believe she hit a speed bump and it knocked the pins out of place. Wanting to know how to fix it what a body shop will charge to repair.
