Can you still be competitive doing that? I'd think the shipping would kill you! I can get my 3M IJ180 with3M 8518 lam countour cut for as low as $3 sq. ft. They roll it up in tubes and ship it to me. That's a recognized, easy to sell and warranted brand name with only one way shipping. I can't buy ink and vinyl that cheap, let alone pay for the printer, the space to keep it, and the people to run it.About 50/50 for me. All cut vinyl is outsourced to a shop I supply with digital prints. It's a unique situation.
BTW: FireSprint does my yard signs.
