I have a 2010 toyota camry LE. I Backed into a street sign while parking and the sign pushed the metal in, creating a dent. It's on the back quarter panel where it connects to the bumper.

Any advice on how to fix this DIY? Is this out of the scope of what someone with no experience can do? Also, is this something that has to be fixed, or is it just cosmetic?
