This is probably a newb question but I was contacted recently by a fairly large real estate company that would like to license and use one of my photos for stock (not sure what that means) for their corporate website. I usually do little jobs on the side so this is a first and completely new to me. They told me to send over a price quote for stock photos so I was looking for some sort of idea on where to start. I don't want to lose the "job" by making some sort of outlandish request. Anyway, I appreciate all advice anyone has for me and thank you for the help in advance.
