As you promo yourselves, don't forget to let them know what is unique about your show and its benefits for the customer. "Your child gets to produce a live dove in a magic trick." "I leave a poster for each classroom reminding them of what to do if they are bullied." "The school gets a free assembly and an opportunity to raise funds in an evening performance." "Last year each school that had the STAR assembly saw an improvement in their students' overall test scores."
Likewise, if you find yourself in a city with lots of magicians you will want to wow them with your unique magic or audience control.
