Wheel Dent

So im in the parking lot at school one day about to back out when this girl in the parking space behind me backs out. She keeps coming and coming and ends up backing into the side of my car. I get out just in time to watch her speed off. I get the tag # and report it to the school "police" Needless to say they do noting about it and how I am left to deal with this on my own since i only have liability insurance on the car. Now i need to find a way to get this fixed. Would it be best to take it to a body shop and have them do it, Bang it out with a hammer and bondo it? If you can see in the photo, there was some rust in there that cracked when she hit it, so that makes the repair a little more difficult. Anyone have a suggestion? Ive already got plans for her car, now i just need to get mine fixed :mad:
