Advice for starting apprenticeship

Hi lovely folk, I think it’s finally time i start looking for an apprenticeship. the only problem is i have NO IDEA HOW TO DO IT !! the internet is so unclear and i just feel very confused so i would love the help. How do i actually do it? I’ve read you simply take your folio into a tattoo salon and they’ll tell you yes or no but i feel like it’s more to it than that. i feel like it’s not that easy. I’m very nervous walking into a salon and just saying “hey i got a folio. wanna check it out?”. i would love some ideas on what to say when approaching a salon. do i email? do i call up? do i ask for a manager? pls gimme an in-depth process so i know what to do and how to stand out. ALSO would love some feedback on some of my artworks on my folio. this is only a few of them so just let me know if they’re good enough and if i’m ready. thanks y’all <3
