Film on Getting in to schools

I am a mom and a documentary filmmaker consulting on a film for a British company who have an agreement to make 3 films for a series called Getting In for Discovery. They're going to follow 3 New York City families as they go through the process of applying for kindergarten. They are looking for a diverse open set of parents who would consider allowing us to film the process...from the August frenzy of pre-applications to the day they open their acceptance letters. They can be a traditional or non-traditional family; they can be applying for public or private kindergartens. Would it be appropriate to appeal to parents through this site?
