Western Sydney Smash Repairer

[XLR83N]

Hi guys,
I found out recently that some ass hole in a car park decided to scratch my car.
Got a quote from Eastern Creek Smash and they reckon it is going to cost me $1000 to repair (bog and fill front gaurd, paint gaurd and bumper and blend bonnet). Seems expensive to me, does anyone out there know (or is) a smash repairer that can or might be any cheaper? I live near Blacktown so something closeish would be great.
Thanks guys!
