The attached pdf document provides a wide variety of grant opportunities other than the typical federal grants. Note: Info on these can be found at: https://www.grants.gov/. This resource is not all inclusive, there may be additional state and local grants - keep your eyes and ears open and don’t hesitate to apply even though the opportunity might not quite be in your organization’s wheelhouse. Additionally, look for free or low cost training on how to develop and manage grants, and how to sustain your organization. A well thought out workplan and budget is one of the keys to a successful application. I suggest purchasing the book ‘Grant Writing: A Complete Resource for Proposal Writers’ and/or other similar titles.
The Appalachian Regional Commission (ARC) provides excellent guidance for developing a grant proposal at: https://www.arc.gov/funding/HowtoWriteaGrantProposal.asp
