Just a point on my experience of this, leaflets take a bit of time to to work. Different scenario as I was selling stuff but people need two or three to respond and for it to register.

Fun fairs when they come just pepper the area with posters which are there and give things a bit of time to sink in.

My opinion - get some posters and drive round Portsmouth, Maidstone and Wigan and get them in every news agents window four weeks before hand. All the better if said news agent is near a school.
