2010 Lancer Rear Bumper Replacement - Pricing??
 

So long story short, my Lancer was reversed into a concrete pillar (don't ask lol)

So rear left side of the bumper is scraped up and popped outta place. I'm unable to pop it back in so seems like i may need to replace it. I wanted to get an idea how much it would cost for the bumper? I know taking it to the dealership to do is gonna cost an arm and a leg, but i just wanted to get an idea of what i'm dealing with...i'm a newb to all this..

I appreciate any help/guidance yall can provide.
