Well since I'm not a professional Makeup artist, I usually charge 30 bucks, but if they buy/bring their own foundation I charge 20 bucks, since foundation is more expensive. Out here in Los Angeles, if you were to go to a MAC counter they would charge 50 buck, so I figure since all my makeup is MAC I'd knock off 20 bucks, but since it's 5 girls I'll probably charge 20.
