do you have money?
if so, maybe making a nifty showroom will be fun...
is it essential? ...no, I certainly wouldn't borrow money to do that...
...put an ambitious hungry sign guy in a chair, next to a vinyl cutter.
Put a production table in the same room with you, go find some work & start doing it.
The success (or lack thereof) of this process, is what your business & your bank account will be built on, not your nifty showroom.
if you got money, then yes... tell us your budget, show pics of your space, & identify your target market & a little of your business plan. With that, I'm sure you can get an abundance of great ideas... but without it, you just get the vague post award
