AKA Tre, Gino is kind of right. You sound like a customer that comes in and asks....
"What do you guys charge for a sign?"
Good grief, what does that mean? There are so many variables. Be specific if you want specific information.
If people on here respond, "I get $3 per foot, oh yeah, I get $4 per ft, me too, oh yeah, well I get $8 per foot, would that really help?
If your making no money doing it for what your charging now, your not charging enough, if you are maknig money, good, maybe you can tick it up a bit.
Charge what your market will bear.
