The body work and paint job you describe is about $20k here at a pro shop.
The other parts and services you are going to need (engine, engine accessories ...generator, starter, carb, etc...interior kit, suspension, brakes, trim pieces, chrome, tires, wheels blasted and painted/coated, radiator, glass, etc)...about $15k.
I generally estimate too low on my projects so you may want to add in some more just to be on the safe side.
The car won't be worth what you have in it, but this is a hobby...not a profit making business. If building the car is how you enjoy your time and money it is exactly the right thing to do
