Looking for Children/Extras for Music Video

I am a Perth Based Producer currently preparing to shoot a Music Video, on a song titled 'Youth is Wasted on the Young,' for a local musician called Ben Hall. We are in need of a large number of Children between the Ages of 5-12 years to take on several small parts, and act as Extras in the Video, which is to be shot in various locations around Perth, including a Playground at Kings Park, and the Perth Zoo. The shoot will take place between the 10th and 14th October 2009, and each of you will be told which days you may be required. Nobody will be needed for all of the days. This is an Unpaid Role, but Refreshments will be provided, as well as Credit on the project. We are looking for as many Children as we can get! There is no audition, so those that are interested can get involved, and no acting experience is necessary! Contact me to express interest at doshinikit@gmail.com, and let me know your availability within that time period too! Anyone that you know, in your friends/family that has Children and would be keen is also welcome, as we are in need of a large number of Extras, so feel free to pass the word around!
