Hello all, a friend of mine had a minor impact with a towbar in her R50 cooper.

Can anyone recommend some repairers in Melbourne? As a young single female she's terrified of being ripped off. She's based in Fitzroy.
I know it's hard to tell from just one pic but hoping some of the more knowledgeable members on here might be able to give a ballpark estimate of what it may cost to repair? Not sure what the damage is like behind the bumper cover and whether or not the crash element may need repair, or whether we could get away with a new bumper cover or just a patch and repaint job?
Many thanks in advance!
