The idea with my business is to reach a great amount of parents that are interested in the service I offer. What I have been doing up till now is sendind letters of introduction to principals in the nearby schools and asking them to organize an event at no cost or obligation to that school......Its not working, any ideas on how to reach my target? Please remember that in order to provide this service at an affordable price a considerable amount of children have to participate at the same time.

Regards,
