Trevor,
If your partners know the intricacies of creating the final product, they should know what equipment they require and what size shop you would need.
You can create the final product with a track saw, an iron, some 18 volt drills, a belt sander, a random orbit sander, a harbour freight spray gun and a few other basic tools and jigs. Oh ya a pickup truck would be good for picking up your material and delivery. You can work out of a garage or shed.
Or you can have a beam saw, a cnc, an edgebander, a dowel machine, a case clamp, all the planers, jointers, shapers, wide belt sanders, dovetail machines, coping machines, straight line rip saws, hinge machines, etc. A complete veneer area with a hot press , guillotine, stitcher/ gluer, and the sanders for veneer. A finishing area with spray booths or better yet a spray line with the finish sanders that go with it. You can automate a lot of it and have return conveyors, vacuum lifts, etc for material handling. Forklifts, delivery trucks and the list can go on and on and on. Working out of a shop that is 100000 sq ft or more:
There are also who knows how many options in the middle.
There are a lot of smart people on this site, a lot of amazing craftsman, but not to be negative , your question is extremely vague and you would need a mind reader to answer it.
