I've organised lots of fetes. We get fairground people to come (they advertise on the internet) and they bring childrens roundabouts, giant slides, candy floss stalls, bouncy castles, and all sorts of things - and they'll give you a donation for letting them come! Also, ring up local ice cream companies who will send an ice cream van along - again giving you a proportion of their takings for coming - and if, instead of booking a burger van (which would also give you a donation for being there), you can do your own barbeque, you'll get the profit from that too.
Also bric-a-brac stalls, plant stalls, cake stalls, a bar selling beer and wine - and we have fancy dress competions, a children's colouring competition, children's races and a tug-o-war too - and the prizes are bags of sweets.
You'll need help - it's hard work - so advertise around the village for that - and also advertise your fete on the 'What's On' websites, and in local papers and magazines - you'll get calls from lots of people wanting a stall there.
With any fundraising event, the secret is to spend as little as possible for as much profit as possible. Good luck!
