workshop for teachers

I'm looking for someone to do energizing activities/entertain/ or do a kind of workshop for 120 european teachers. I really want something that could be done to start the day at 8.30am, just for 30 mins. We've come up with some ideas that could be interesting like a dance class, jazz class, tai chi pratise, icebreaking activities. This is not a corporate event but for teachers, the main goal is to entertain and warm up for the event..does anyone know anyone belgian based?
