Watch the interview videos. If you don't have any tattoos to show that you are serious to even get into tattooing, most shop owners will see this is just a "lust" to get into the business. If you are serious, start getting tattooed by people work you are into, and try to build ontop of that.
Sorry but drawing a few months and walking in with you're art isn't going to work. You need to know how to paint, do layouts, know what makes a good tattoo/design and what doesn't. You just can't get into tattooing with having some "months" of drawing, unless you have been an artist before considering this as a profession. To the guy above that said go on e-bay and get a kit, and fuck up whoever is willing to get tattooed, don't do that. Chances are those people getting fucked up, will go to a shop and see your work eventually. Don't buy machines off e-bay, you aren't supporting the people in the industry, and they run like shit.
Good luck with you're adventure, most shops won't take anyone, as of now, it is VERY over-saturated with a bunch of people in it for the wrong reasons.
