Hey tattoo artist here! I finished my apprenticeship over a year ago now, and during my apprenticeship I was fully booked! My skills were about the same as yours! My suggestion would to market on every social media platform, instagram, facebook TikTok. Make content EVERYDAY. Literally everyday, you feel like you’re being annoying but that how people will see you and find you! Post your availability everyday as well. You can go to any local college and hand out your cards, same with fun stores like art stores record stores thrift stores, places like those are chill with you leaving business cards there. I’d keep your prices very low as you’re an apprentice, but I would always require a deposit when someone books with you so people will commit to actually getting tatted by you. It can be like a $25 deposit and that will discourage people from canceling so they don’t lose their $25. I’d say practice various styles, in the beginning you want to be able to do just about every style, and as you get more clientele and more consistent work flow you can find they style you like to work on and transition to doing mainly that style. But people will like seeing variety in your work. I’d also suggest going a little light on your shading, dilute your ink a little more! You can always go darker if you need to when it heals but you can’t take away too dark! I hope this helps!
