Think about ‘selling’ the message, the message being the value you provide to your community. Your goals need to be things that your support network can ‘get’. The more your goals relate to your community, the greater the potential for buy-in.
Think laterally about how you can benefit families or members in low-cost or no-cost ways such as establishing community awards or funding low-cost projects that engage children, be it a photography club (fund the cameras and recruit a parent volunteer to run a 10 week program) or a Lego club (with a spare room and donated unused Lego where a weekly lunchtime can be dedicated to Lego building).
The more tangible the benefit (or range of benefits), the more your supporters and potential supporters will connect with your purpose and support your fundraising efforts.
