I have a chance to have an airshow act maybe use some of my photos I took of them in action to promote their act on their website. The question is how much should I charge them? Here is the site in question: http://www.airshows.com/dacy/home/ If you click on the link for the pictures you can see how poor they are. If you check out my Airshow/Air Racing gallery you can see my photos are just a little bit better. So what do you think??
