I am a certified makeup artist, and you can be paid well depending on the route you go, and what the demand is for makeup artists in your area. If you just want to do smaller projects like bridals, prom, etc., what you make depends on you. But if you get involved with the film industry and get qualified to work as a union (SAG-AFTRA) makeup artist, you can be paid about $1000/day, depending on the project and your contract. You could be paid more if it's a big budget film, but at minimum, you can be looking at the $1000/day.

Probably the ones who get into Movies/TV do pretty well for themselves.
