Anyone near midadlantic, sketch out a bench design, order some cut to size 6x2" to make up the frame, some 8x4 sheets of MDF, a couple of drill bits, some lag bolts, some locking castors, and get them delivered. Might as well chuck in a drill driver, some clamps and a speed square. Send over the invoice, with designs to follow on payment.
Assembly'll take a couple of hours, as it does with almost any bench (you know, time to research, find, order, receive, unpack, sort out the bits, bolt together, square up...)
