Tort tables are really, really easy to build. If I can do it anyone can! I built a 4 x 3 table for my Greek out of 1 sheet of plywood, that was enough for the bottom and sides (I made them a foot tall). I did use some 1" x 2" in the inside corners to add stability and as nailers. It really was just a matter of cutting the bottom piece to the desired size and then cutting the sides to fit and screwing it all together. A coat or five of poly later and it's good to go.
I looked around for something pre-made and really could not find anything that was suitable but, as I said, this was super easy to make.
