No pics showed, but I'd check with your local body shop. They can handle the welding for you, and depending on severity and location, they may be able to patch it up without removing the body. That will save you tons. If you need extensive frame reconstruction, you're likely looking at some major bucks, and if you're going to go that far, I'd suggest thinking of all the mods you want done, and trying to do a proper frame up restoration and rebuild. It's a good chance to do an SOA conversion and to replace all that rotted rubber with poly.
