Knowing a Welder helps, a machine to use weldless fitness is a plus. You could also try a plasma cutter at a local machine or sheet metal shop. Good one's Vermont get 65.00 an hour, which is litittle bit more then the cost of the materials to do it solo where I live. The plasma cutter dued can usually be bribed with homebrew.
I guess it all depends on one's pricepoint.
