I need a letter to ask for donations for a church building project. We are trying to build a new church . I need a template so we can ask for donations from different individuals. Also i need a letter to ask different corporations to give to a non profit church building project . A third letter to ask a dealership if they would donate a van so that we can help people in our community to get to church . Total 3 different letters asking for donations. One for individuals, another to ask from corporations and a third for a donation of a church van.
