Working with a registered charity

Is the charity you are working with a registered charity? If so, they probably already have information leaflets, an office and some full-time staff to support you.
How do they support their cause?
Is the money raised used locally, nationally or internationally?
What do supporters see the charity achieve?
Do local people benefit from it?
How well known are they in your local community? The better known they are locally, the easier it may be to gain support.
What are their overheads?
How much of the money raised actually goes to help the projects?
Can you be sure that you are helping the target group and not just paying for administration? (E.g. some scratchcard 'charities' only donate a small part to the cause while the rest pays for administration and prizes.)
Who is the local contact for the charity? How easy will it be to liaise with this person? How can you communicate with them? A PO box number won't be much help!
