What to do when asked to sell a picture?

Yesterday, I was approached by the editor of a well known magazine publisher via email and she wanted to buy one of the pictures on my blog for use in their October issue.



Since I am not a professional photographer, I was of course, thrilled and flattered. I was like, "Wow! Somebody got interested to buy a picture taken by... me!?" and I am not even using a big-ass camera! It was all a good experience, except for one thing. I have no idea what to do and how much should I sell my pictures for???
