First thing to do is try Craigslist. If you have no luck build them. Purchase the legs and build the tops. If you build the tops an easy short cut is a door. Yep a door. Look for an old solid one with out a window. A class room door from a school or an office would be the ticket. Usually they are made of maple or oak. Even a small window would be ok because if you removed the glass the remaining hole would be nice to sweep stuff into a trash basket. Think along those lines that's what I would do.
