I have a local university that wants to contract me out to do some aerial photography and video of the campus for them with my Phantom. Basically I've gave them a rate in which they get 5-10 edited photos and 3-5 edited video clips in a package, set rate. Should I be getting a piece of the pie since they are using these for promotional use on top of my rate or what's the smart thing to do in this situation? I don't want to screw my self and I'm new to the license/royalty game for photos. Thanks for any help!
