I'm sure they won't mind! Uh, I'll start linking you everyone but Ty-s, who commented below me.
Okay, in order. If he owned Living Ink, Ty would work for him as well as bltaccetta.
bltaccetta is dating my chick rainek. Raine shows up at the tattoo parlor often to visit Birch at work, or think about new work. She needs someone who would be willing to let her apprentice under them for shits and giggles. She owns Hell City, but has been learning things from Birch along the way.
With Ty, he lives with Lucy here who would visit often. Ty's little brother is titan_trandon and Trandon is dating trevor_luxx though in secret for now but yeah. Add to all of that, Ty and Lucy both are sleeping with feelin_fallon who is bffs with Raine. It's all a huge circle.
As for them being up for it? I assume so. You can knock a few birds out with one stone, since Tran-s and Fal-s are the same person, but Birch-s and Trev-s you'd have to contact on your own! I am totally whoring you out though. I'll give Fal-s the heads up.
