old plastic trash can 32 gal (Charlottesville near chs)

I'm looking to cut up an old plastic trash can, to fashion for myself a piece of plastic that I can lie upon, on my back, sliding underneath my car. To fashion it into a "creeper" for work under the car. Stupidly, I recently had such a trash can that I retired, because it was starting to crack / deteriorate, and I had the city take it away. D'oh! Now I realize I need something like that to fashion my ultra-low, ultra-thin creeper. Has anyone got an old trash can like that, no longer needed, made of plastic, out of which I could cut a 24 x 36 piece of plastic (or some such size)?
