Help needed to fund a charity motorbike ride

Hi my name is Steve. I work for a charity supporting adults with learning difficulties. There are 14 at the home I work at and they do so much with the residents. The surroundings are lovely and it's a lovely place to live. But they are a charity so anything they need they have to fund raise. I ride a 125cc yamaha and plan to ride from John o groats to lands end to raise money. I ride on L plates so it will be all off motorway. I'm looking for any help I can get for everything from equipment, and fuel to accommodation. I plan to do it over 5 days during my off duty at the beginning of September. So any help you can give me i will be so grateful. Every penny and every pound will help.
