I have someone who wants to use my photos for commercial purposes and I want to charge them. What is the proper way to sell them? More specifically what is the proper way to license the photos and do "shared" licensing rights?
I want to use paypal to receive the payments, is that all I should do or is there some written legal documentation that is needed?
P.S. I would just like to send them in digital format through e-mail to the buyer.
