I need to replace the floors

I am unemployed and have been since july 08, with no unemployment benefits. So waiting to buy pans is out of the question, I have a friend who can weld in what ever I come up with, so that is covered. I have access to 18 gauge sheet metal, and have thought about different way to make the beads in the floor. I want to get the car back on the road, cuz if I can't afford my truck and they repo it I need something to drive. I am trying do things with no money, as i am not sure when I'll get back to full time employment...
I want suggestions, ideas, tips anything to help me do this the easy way not the hard way..............
