I would love to have found such a resource near me when I was trying to build my table.
Some good news for the rest of us: with clever design courtesy of Ryan and others, a CNC cut table, with ribs and struts cut from plywood, can accommodate full sheet cutting without needing any sheet good larger than normal full sheets. I drew up and posted one version of this recently here on site, and Ryan has pledged to work on completing his design of it when he can.
