My hometown has asked to use some of my images for billboards along interstate freeways in Indiana to promote our hometown in Michigan for tourism. How would you charge for that? Do you charge a flat rate for the image, or charge a monthly fee for as long as its used on the billboard?
You need to determine the usage for the billboards.....how many and for how long. It can be a pretty sweet payday if you can agree on the full price but small towns are usually on pretty tight budgets and they may want some pretty heavy discounts.
