I have been contacted to take some pictures for a boxer in a fight he will be in next week. He wants the action pictures for internal use within his gym and for his sponsor. I talked to him about signing something that says if they want to use the images for any external purposes then we would need to work something out. What do I need to put in wriiting and have him sign so they can be held accountable? As this is my first experience with this sort of thing, I could use any comments or suggestions that you guys could help me with.... Thanks!!!
