"He who marches out of step hears another drum." ~ Ken Kesey
I could find out for you about the laminator.My main advice is don't plan what you need for now, plan for what you'll need when your customers find out they can get all that other stuff from you. Throw in contour cut graphics for vehicles, signs, I even do stickers for the backs of medals for sporting events and plaques.Then get the printable t-shirt vinyl and print and contour cut full colour graphics and press them on for jobs where it makes sense.then get the flag media and start doing the banner flags, pop up banners, trade show back drops etc. etc.
My $0.02 another route to look at is a Cannon IPF printer and a stand alone contour cutter. Until you can afford the laminator they make some great spray on laminate today. Not as good as a laminator but if your on a budget it will work.
