I know musicians who are self-taught and they're monsters on their instrument, but I also know musicians who can't do squat and I know musicians who have had much training. While the well-trained musician can do a lot, he might not have the same feel, but technically he/she is good. There are other professions which will allow one to get into it without any formal training or knowledge and those are the very people I would steer away from, if I knew ahead of time, they were hacks. Doctors, marine biologists, anesthetist or a physical therapist to name a few....... would you want them to learn job by job...... on you ??
The difference between someone who trained or went to school to be in the sign industry and you is, they have a basic hands on background.

I'd like to see that look, when you tell the customer, uh, yeah, we can do that, cause we just push a button and it works. Between the software and our distributors, we have you covered. No one has any real hands-on practical knowledge here, but it should work.
We flatbed print our magnetics, so we have no real issues with what most here are complaining about, but when someone gives us a plastic or aluminum vehicles, we hafta give them the bad news right up front, instead of having someone come back and make us look like a fool, because we didn't do our homework.
