My FSIL is in the makeup industry. I asked her her for professional makeup artist contacts, but instead, My FSIL offered her own services. She's very talented, so I happily accepted. In fact, the only reason I didn't ask her to do my makeup in the first place, was because she's in the wedding, and I wasn't sure if she'd have the time. She told me not to worry about that...she'll bring a friend to help. My question is, how do I handle the payment? Would I treat my FSIL like a normal vendor?
