Hello,
I am new here, but I had the same struggle :D Few days ago I went to the tattoo artist (I don't know how it is called in English, tattooer?). And on 9 of June I am going to do tattoo on my forearm :D Just relax, think what you want and bring pictures. I think all tattoo artists are honest and friendly, so you don't need to panic. I can't wait until I get my tattoo :D
P.S sorry for bad English, because it is not my native language :)
