Hey Lin!
First off, welcome!
Secondly, In my opinion, you should steer well clear of getting tattooed in your friends kitchen, or anywhere that is willing to tattoo you under the age of 18.
Best way to approach a tattoo idea, is to gather a few reference pictures that give the tattooer enough of what you're after and let them run with it. Keeping in mind they do this everyday, you'll get a much nicer tattoo this way.
Other than that.. you seem eager, which is great, but please take the time to think your idea through! Nothing worse than a tattoo you regret.
Welcome again, and enjoy your time here!
-Tim.
