I have a friend who is going to do my makeup for my e-photos. She is not a professional but I would consider her an expert (she has a blog, etc). She suggested we do a trial (more to have extra time to hang out since I never see her). I told her when I asked her to do it that I would be happy to compensate her for her services. I'm at a loss for how much that should be though. What would you all say is a fair price?
