Ideas how about
Quiz night, ask your local town to help, by asking for donations from local shops to use as prizes.
Guess the amount of sweets in a jar.
Asking the people at work to sponsor you, and tell them for every pound they donate they will be automatically entered in to a free prize draw, the only thing you need to do is send out begging letters to big companies and local ones asking for donations for a raffle, which I have done and had some good results.
It's hard work trying raise money, so if any of the above help fingers crossed.
