I have several pages of my build thread (link is in my signature, right underneath this post) dedicated to the body restoration that my car is currently under-going. I HIGHLY recommend the panel beater I am using, but there is a wait list to get in and the work itself will take the better part of 12 months as well. You will not find anyone as good or cheap in Perth, I can guarantee it.
My car is still in the shop if you would like to go see it in the flesh this Saturday morning and I can introduce you to Will in person. You can chat to him about the work you want done, it's almost identical to mine.
