I shoot real estate video and one of the services I offer is shooting community locations to go with the home walkthrough. I charge $100 per location to shoot. A realtor that I work with has a lot of homes around this area and would like to include the community highlight that I shot previously in all of their videos. How would you charge for this? The work has already been done for a previous project with this realtor and this would be a simple copy and paste for me as far as editing goes. Is this something I should charge on a per project basis regardless of whether I already shot the footage? Should I offer a higher rate to outright buy the footage to be used as many times as needed?
