Hello out there, Jus picked up a small job,12 shirts (cotton), Navy blue, All they want is two letters "DC", 3' X 3", right under the front mid collar. I'm new to heatpress vinyl pricing, so I'd like to be very careful on how I charge. Want to build clients, not scare them away, but not give them away either!! Make sense? If anyone could help me I would really appreciate it. I was kind of thinking to charge like I do my decals, but am I thinking wrong?? Thank you for your help!!
