shortening a long bed, would you do it?

[SnS C10]

hey guys one of my good friends recently bought a long bed for his 65 c10 shorty frame. He asked me if i would shorten the bed for him as he does not know how to weld. He said dont worry about the bed wood or any of that. Just return it to him as a shortbed, with the welds ground down. He said he would pay me 700 to do this. I would have to buy saw horses and some supplies totaling around maybe 150-200 bucks. What do you guys think? Is it too much work involved to take him up on this offer?
