Summer Kids Sporting Activities

I require material to be produced advertising the Summer kids sporting activities which will be taking place at the leisure centres over the Summer holidays
The material should be vibrant and appealing to children (5-11 yrs) and should have a sporting theme. With the Olympics taking place during this time I would also like this incorporated into the designs
I require A5 flyer (double sided) / A2 poster / Banner (8ftx3ft) and would also like the poster in jpg format so that it can be e-mailed out
The information about the activities being offered will be provided and the design must incorporate the Kids Activities logo (which will be provided)
I am looking for a quick turnaround from 1st draft to completion
