Casting: children 6–9 years for background roles in a film

Looking for background actors: boys and girls aged 6 to 9 years old maximum. Mainly European children but also various nationalities. The setting is a rather bourgeois school in a close Paris suburb. This is urgent as we will be submitting files very soon, even though filming will take place from 28 September in a very close Paris suburb. Cinema extras rate.
