Actors for Child Seat Demonstration (May 9th)

I am looking for actors (with children) to demonstrate how to use different types of child seats for a business. Will be filmed by me in a clean minibus with my camera equipment. I envisage roughly 10 videos which will have a running time of roughly 1 minute each. 2 people needed right now: middle aged, male and female, british with professional appearance (bonus to bring a child). Can pay £100 per person. Sutton based.
