Nice machine.
Anyway, ask them for a floor print of exactly what your real estate is gonna take up. For a 5' x 10' you're either gonna need 2 people or a machine to put some of your big stuff on a machine like that and rather carefully. It would be nice to know where you will be putting this stuff on and getting it off, if using full size sheets. Even pre-cutting things, sometimes you will be called upon to do bigger than expected sizes, so best to be ready out the gate with those things. Also, pre-cutting things is not necessarily the way to go. That'll be a lotta start and stop and re-alingning things, where doing a full sheet of 10 up would be a lot more economical from many viewpoints. That's the way you do your offset stuff, right ?? No different.
