I'm looking to have a roll cage made for the dune buggy I'm working on and I was trying to get an idea of the cost. I pretty much want exactly the same kind as in these pics, four corner mounts and the rear. I looks like theres only really 4 bends, making the front and rear loops. The rest would be the concave end cuts and welding it together. I also want to work in a roof rack system so I'd be able to switch out between a safari basket, surfboard and bike racks, probably Yakima since I have the board and bike holders already for my Audi. Any ballpark numbers and builder recommendations are appreciated.
