that sucks man.
advice for anyone building - although not always possible, try and get your parents behind your build. once behind, if you ask them for help for supplies or skills or whatnot, its soo much easier. also, once you get em on ur side, they offer things too. As soon as i got my dad on my side for rails/boxes, hes gon hook me up with a friend of his who's a pro welder. as i said you can't always get it, but when u do its so sweet.
also, ur dad or uncle doesn't have to be a carpenter - if u no anybody who is, or if u find any hardware stores (rona, home depot, etc) you can always ask them if they have any spare/scrap wood. if you take the time too look, sometimes you'll get big sheets of wood, or relatively long beams (simply cuz they weren't big enough for what they were ment for)
