I'm going to have an interesting fall, but its time for some preemptive thought.
To make a long, kinda interesting story short, I shoot for a yearly publication in Minnesota often called the "Encyclopedia of Minnesota High School Sports." They have been publishing a football book for six years and now have four others sports - including my own, hockey 
They also host several tournaments for basketball each year and let me have full access to anything I need to advertise photos for sale. I did my first tournament last weekend and have received tons of hits and a few requests.
The owner knows many, many, many coaches and is willing to contact the coaches prior to the game - to refer them to my website.
The problem is that there will ALWAYS be coaches/students who don't care with parents who do, but don't know.
That said, how do you effectively market photos to an audience at a fairly large high school football game? I can make cards or whatever, but I'm hoping for other methods.
Thanks!
Otherwise have someone handing out cards and fliers to the people in the stands during the game. Of course if you're shooting you'll need someone else to do this.
