Turning up to a new place to try to get people to back your crowdfunding product is a bad idea. I've backed many Kickstarters, but I learn about it organically and find out for myself.
Also, this isn't going to work. My artist has a degree in art and can draw anything I need him to. The vast majority of tattoo artists aren't going to tattoo something you brought in from some nobody who has never tattooed. They will laugh about your request after you leave. It's just not how this works. That's not how any of this works.
