Volunteer to wash the cars of those living on your street or nearby, in exchange for a small donation towards your sponsorship total. To raise a greater amount, ask your workplace, school, clubs you are involved with or local businesses if you could use their car park for a fundraising car wash. Rope in other people to help you and charge passing motorists who would like their vehicle washed.
Speak to your local pub about whether you would be able to host a quiz to raise money, with entry fees going towards your fundraising total.
Offer to help family, friends and the local community out by doing some of their chores – take dogs for walks, babysit, do some ironing etc. As you are helping people out, they may be more generous with their donation.
Car boot sale
Have a root round your house for any unwanted clothes or gifts, and either sell these items on eBay or arrange a car boot sale. If you make it clear where the money you receive for these items will be going, then customers may be willing to give a bit more for them.
