Advice Please!!

Hi! I'm Rylie. I'm 15 and I'm thinking about pursuing a career as a makeup artist. I've looked into schools, but none of them really have what I'm looking for. Most schools make you go through a hair + makeup course or esthetics(spa) + makeup course and I'm not interested in either hair or spa. Are there any schools that anyone knows of or has attended that could be what I'm looking for? Location of the school is not an issue, as I am willing to go anywhere for my studies. I am already somewhat experienced in makeup(yes, I know I'm only 15😂), so what I need to learn is really just sanitizing and the business aspects of the job. Any advice is greatly appreciated! I hope all you lovely ladies have a wonderful day!💞
