Damn bro! That really sucks. I know the area you are talking about. I had a fender bender similar to yours in my 335i and my rear bumper had a small indent. Not to noticeable but it cost about $1200 to fix it up.
I would recommend getting some estimates from other shops in the mean time like marnello or national collision until Screamin Paintworks opens up and make sure he is aware of how much he will have to pay.
