When we replaced the body mounts on our 95, the radiator support was off in the front. We loosened all of the mounts, then took them off on one side, jacked the body up on that side and blocked from the frame with 4x4 blocks to give us room to work.

Is it the frame mount holes that are rusted or the cross sill crossmember or the inside bed floor? There would be different fixes depending on where you have to patch. If you space the back mounts with frame savers, you may need to space the other mounts the same amount so the body isn't trying to bend.
I have no idea what the cost would be for someone to repair it. You may be able to set everything up and find a welder that will come out to weld it for you.
