The primary cost of a professional paint job is the preparation. Perhaps you could take your time and do all of the body work yourself and then take the vehicle to Earl Scheib or Maaco to have the final spray done. Then, back to your garage to wet sand and buff and re-assemble. I bet this would be cheaper than a rattle can solution and look much better. Another option would be to turn it over to a local vo-tech or highschool shop class to learn on. They may do it for the cost of materials.
