Body shop for rear bumper install...?

I realize that a rear bumper install is pretty easy, and I should be able to do it myself. That said, I would prefer to pay a Seattle-area shop for the install in the event that I need to file a supplemental claim after a rear-end collision.

Do you guys have any suggestions around shops that would be open to doing this work if I provide the bumper? I would prefer that they are familiar with the claim process (not sure if Mule is/isn't but they generally won't install provided parts from what I understand.)

Thanks!

 

They'll install parts your provide but the shop rate is slightly higher. Can't remember exactly what the rates were.
