Flyer advice

I am fixing to put out around 5,000 flyers in several schools in my area soliciting kids to join a correspondence entrepreneur school. They will be allowed to sell discount cards and will earn a commission from every sale and will compete for prizes, cash bonuses, and scholarship money toward a college education..My original thought was to charge $20 bucks for a 1 year enrollment but I was also thinking about putting on my flyers to let them join for free but charge them $10 bucks for there curriculum so what would you guys do in my situation?
