I was asked to create a portfolio for some one i dont know she wants to become a model. I have done multiple photoshoots for friends for free but i was wondering how much i should charge her? should I do a flat fee or an hourly fee? She wants some pretty basic photos, im thinking some with a white backdrop and some with a balckdrop depending on the outfits she chooses. Any advice greatly appreciated. EDIT: The shoot is in 3 weeks, I wil post pictures afterwards for critique.
