I've heard of people having good luck with the hardwood countertops from Ikea. If you've got a miter saw, table saw, and electric drill/driver, you could probably come up with a pretty quick to build 2x4 frame, and mount the countertops on top. Doubled 2x4 for legs, cut out mortises for stretchers before you glue them, and fasten everything in place with lag bolts. They won't be pretty, but I'd expect you could set up a production line and have the frames built in a week or so.
You didn't mention size, but you could also find a company that makes custom desks, and ask them to fit tops with a foot or so of overhang on each end, then just bolt vises to them. I'd prefer wood (both for looks and interaction with sharp edges), but it might be faster.
