Also see our other questions to Ask the Institute . The issue here is continuity because you put an endowment away for perpetuity. Have run a budget in the black for several years. Have a least 1,000 regular donors.
Donors shuld be able to leav assets to the organization.
One strategy is to make use of your local or regional community foundation, which is set up to provide endowment services for local non-profits. You can also contact the Institute and get in touch with one of our fundraising consultants.
