How much would you charge for senior portraits?

I'm a high school senior. I have a nikon D3000 and 2 different lenses.
A (somewhat) friend emailed me for senior pictures, because i post all of my photography on my facebook. She's asking how much to charge, I've never taken professional senior pictures before. How much should i tell her?

It depends on if you are including a disk for her so she can print as many photos as she wants, how many poses and backgrounds. Are you printing off photos for her? You aren't professional so $50 or less would be a good fee.

Unless you have your business legal ducks in a row (business license, insurance, tax ID #) I wouldnt charge anything. If you are not a skilled professional (which it sounds like you are not since you said you have never taken pro pics before) then consider it great practice & portfolio/skill building.
