Paying for bridal party hmua

Hi! As a bride, are you obligated to pay for your bridal party’s hair and make up? They are all flight attendants and they know very well how to do it but since they’re coming from different parts of the world I feel that they’ll be spending more than enough just to come so I’m thinking of shouldering their dress and HMUA. I found a great hairstylist (they own a salon) and does make up too but they have just 7 photos on their portfolio. It’s going to be just $95 each HMUA for my entourage (I have 6 plus my mom and fmil) so I think that’s already a steal. But they are 2hrs and half away from where we live and that makes it difficult for me to get a make up trial which I think is necessary. I’m not particular with how they want their hair to look but I’m concerned if I should hire them and just get another make up artist just for me. They do just traditional make up and I want to have an airbrush. Should I go for it?
