Re: restoration
Well most local body shops will take on a project like this. Try and find a couple (non franchise) body shops and see if they do side projects. It will cost a decent amount over just a paint job but not horrible if the place is fair, but it will probably take a while especially if you are switching bodies completely.
Other wise you can check with street rod/ hot rod shops and go from there. You can save your self money by dismantling the interior and such and re-installing it your self, but make sure to keep very good records and organize the parts well. Bolts all start looking the same after a while.
Good luck, post some pictures up of the areas of concern and maybe can get you a better idea.
