How much would it cost to repair or pop a bumper back into place?

I recently got into a fender bender in which I rear ended a 2002 Honda Odyssey with a 2007 Honda civic. The damage isn't all too bad except that the van's right bumper that I hit is out of place and looks like it needs to be popped back in. The car I was driving has scratches and a small piece missing but no dents at all. The problem is that it is my roommate's car and she is not insured for it, it's under her mom's name. I'm taking full responsibility for it because we do not want to get anyone's insurance involved. We got a policeman involved so it was easier for me and the guy to have our information. The guy is going to a repair shop in the morning and is going to call me with all the costs of the damages and I'm going to pay for it outright in cash. I was just wondering, how much something like this is going to cost? Thank you for anyone who can give me any information at all. I'm extremely upset at myself for this and as a college student, I just hope I can get by without putting a huge dent in my tuition savings.

Use Insurance. Or expect a grand in cost(bodyshop rates have skyrocketed) It will easily eat your tuition money away. And all shops are like that or higher.
