A charity football match

How about putting on a charity football match in order to raise the funds for the astro turf? You could try and find a few local celebrities to come along and commentate, or even play! Ask each supporter to contribute a small amount of money in order to be able to come along and watch the game, and sell homemade cakes, drinks and other treats at half-time in order to really get the money coming in. All proceeds of the match can go towards the cost of a shiny new astro turf pitch.
