Am I paying my part time assistant enough?

The job is remote. She makes $50 every time she schedules someone, which is guaranteed less than an hour's worth of engagement per person. I currently book about 3-6 people per week. I'm giving her a $100 base pay per week for posting stories and tattoos, monday-fri (which is a once or twice a day thing, but some days I don't have a tattoo to post) Timewise, posting takes 20 mins a day if that. On top of that, I'm giving her a free monthly tattoo of anything she wants, no limit on price, just a whole day dedicated to her.

She's also a great friend of mine. She won't tell me if she's being compensated fairly for her time because she believes in me and wants me to do well 😭 Is this a good deal or a terrible one? I've never employed someone before, plz go easy on me 😅 I would pay her so much more if could, and that's my goal eventually. So far I'm trying to give her enough for part time work.
