I went to the metal savage yard and the charged me by the pound and it was real cheep. Back breaking but cheep. In the future i ame planing on building it from wood and painting it, becuase it is just about as easy as what i did. I did the all day room build with bad boys seanic design at trans world and they built the items in there's for less than I could go find it for free. Look for some pics online but it was all made with hard board and plywood and took no time at all. The finish on it was Brutal Rust paint and that worked great and was not tough to do, made the wood look like it was rusty steel. They also did a faux rust on a barrel that took all day that I think looked great but not great enough to spend all day on, when the Brutal Rust took as little time as rolling paint on a wall. They also use a lot of PVC pipe and I was surprised at how realistic it looked with a little spray foam for texture and spray paint for color. Good luck on your build and hope you can find what you are looking for.
