Are you clear about exactly what the project you are trying to get funding for will be and who it will be for?
Try explaining the project to a critial friend, who doesn't know about your project already. Does the project make sense to them? Is there a clear link between the people who will benifit from the project and those who are in need of help? Is it clear how the project interventions will achieve the intended outcome?
MVSC can give you hands on help with this and direct you to local strategies and plans that can support your bid, and delivers training on fundraising.
