I spoke to a tattooist, today. I e-mailed him the Ouroboros Tattoo that I designed, so he knew what I was going for and had a basis for his no doubt far superior sketch.
By the end of the month, I should have my tattoo done.
The artist I'm using is a guy here in Phoenix named Seth Alexander; he works for the Phoenix Tattoo Company (which, oddly, is in Tempe). This is their website, and here is a selection of Seth's work.
