Fashion ~$50 – $200
Beauty ~ $130 – $320 (sometimes even up to $500, if everything have to be perfect even on extreme big print, and there is a lot of work with hairstyle etc).
Portraits costs much less than for beauty, but it's hard to even give an approximate price without seeing the photo.
For work that must be done in less than 10 days – additional 30%.
