Good evening. I was asked at a soccer game this past weekend if I'd be willing to take some shots of one of the mom's 23 year old son. Her son apparently was interested in modeling several years back and would like to get back into it. She asked me what I would charge and I really have no idea what to tell her. I told her I'd get back to her this week. Can anyone give me advice as to what I should be charging? This would be my first paid job. Along with price, any advice regarding number of wardrobe changes, etc. will be extremely helpful. Thanks for your help!
