wow $85 here that would be 0 profit that would cover pvc vinyl and labor only,especially double sidded
Then you are in the wrong business, cause I know people who live right next door to you that could make a screaming profit at $85.
For us to produce that image on both sides of a 22" x 30" would cost us not quite $5.00. The $85, I spoke about would be to keep it honest, so not to undermine the industry. If I had 50 of those to do and did them for $15 a pop, I'd make a killing. At $85, it would be fantastic.
Remember, you're using about $3.50 for substrate and going about the graphics portion wrong, so there is why you can't do it for an honest buck. Fair market value is where one needs to be. The day I'd pay the kinda money you're indicating.... is the day I can retire.
