Recovering a Seat

Worst case senerio.. Customer brings in a seat that looks like a bomb went off in the drivers area. I'll have to go to my bone pile and find some springs to replace 2 or 3 broken. rebuild the filler or even worse the owner has striped the core down to bare frame so I have to build filler from scratch. If I can't get a matching reproduction skin I'll have to order material and make the skin. Wait, I just noticed the back frame is warped and doesn't sit up square, or maybe there's a small crack in the base frame. Either way I've got to carry it to the body shop 2 doors down and get it fixed.
So yeah, not knowing what I'm starting with and knowing what I've seen before,
I would estimate as much as 400.00
