Aaaa so busy

I keep doing so much commission work, I’m finishing up 4 of them right now. It takes so much of my time, but I never feel comfortable pricing them based on how long it takes. I know I’m under charging my work, but I feel like if I price them honestly I won’t get any customers since I don’t have tons of followers. It’s so frustrating. And I need to make more money so that’s hard too.
