Frankie,
I'm sorry, I'm with MsRad. I know many, many talented tattooers, can't think of a single one with an apprentice. You will have to draw for many many more years, not months, and you should wait until you feel like you ARE a great artist before you approach anyone. And for the amount of time it's going to take to get from where you are now to earning a living might take longer then becoming a doctor or a lawyer or a airline pilot. That article on building a portfolio is great regarding building a portfolio, not sure its a surefire way to get an apprenticeship, but I bet it'd get you into art school. Wonder how they came up with the "Time Required: 1-2 Hours?" Maybe that's how long it would take the average person to walk to and from the art supply store to buy the portfolio?
Here's a thread that I love, you might find it eye opening:
