WTB 1965 Impala Passenger side quarter panel

I need a complete clean 1965 Impala passenger side quarter panel for my 1965 2 door. Or is there a good auto body man out there that can weld in the quarter panel piece I already have? I also have a new wheelhouse just in case it needs to be replace. Hard to find parts on a 60 year old car. I would appreciate any help as I have been scammed before over this.
