How to find volunteers for a charity
Be knowledgeable.
Ensure that you have all the knowledge of relevant topics associated with that particular charity. The more facts you know the better you can answer any question that the person you approach may ask.
For example: what is it all about? , who benefits? , why would anyone want to support that? , will it improve my community? , will my efforts make a visible difference? Have all relevant documentation with you. Ask the charity committee for any information they can spare (on paper).
