Slappy, this is something that has been happening for a long time in the
sign industry. However, with the
computer doing most of the work, it can be done quite easily and almost everyone knows it.
You can set up a new way of introducing people to your design/layout upfront charge and probably tick off most everyone or you can be [
somewhat] honest with them and tell them your design is in a proprietary format and needs to be converted for them to use as they need. This process will require a day or two to manufacture and your starting fee is.... $195. Nothing accompanies this file except a receipt... PAID UPFRONT. If they wish to have the file in various formats and have some slicks or separations included, it's $375. This gets rid of the lazy people who can't do their job properly.
How many times do you.... or anyone else in this place, get crappy artwork to vectorize or mimic without any additional help. We manage to do it, so.... so can their peeps.
Like Joe said, if someone approaches you and you can tell you're gonna need the various tiers of pricing out a layout/logo design, then it will work. Otherwise, how many people just say... I want my truck lettered ?? You do a mockup and they fall in love with it and
THEN.. want the rights to it.
