Sorry to hear about the accident, Yikes.
The cost all depends upon how well you want the car to be repaired. If you want it like it was before, it will take new fender, turn-signal/side light, possibly headlight, hood is messed up, and of course the bumper and apron. You could probably spend over 1k in parts alone, then there is labor and paint. I think you are looking at 2-3k to do it 'right'.
Then again, if you are not real picky, the $700 might get it looking ok...not great but ok, maybe. Junk yard parts are key to keeping the cost down.
