Typically, you start with an idea, then the person who will be doing the vinyl can computer generate whatever you want and print it out on vinyl. As for price, it can vary. Im sure there are plenty here who can tell you what they paid, but you'll have to call someone who does it to nail down your price. I've known Painterchick for some time. She stays busy, but is considered one of the very best in the business. Can't go wrong there!
