What about just getting it repaired by 'Z-Shop' in Glen Iris? I did when I had a prang many years back (not at fault, full comp insurance). Just had the car taken to them, they did all the quoting, have a huge amount of spares on site & can source anything they didn't & then they organised the painting through a trusted spray shop. Possibly worth giving them a ring for a chat at least. Don't try to get the car home & repair yourself mate, it'll will end up taking ages, just find a good repairer your comfortable with & let them sort it. I'm sure Shannons can recommend plenty too themselves.
