I can help research organizations that might be interested and get mailing and application information. I can also research ideas that you send on what your proposals would be. Then cover letters and samples of work would have to accompany the grant proposal as well as estimates of cost and expected results from the documentary proposal. Should I contact you through your website?
Have you thought about grants. There must be organizations or magazines that would sponsor a well written proposal. National Geographic Magazine, United Nations, Greenpeace (environmental concerns) come to mind and there are probably more possibilities.
I found your blog through a member who is following my blog. I am impressed especially with the forest and environmental concerns. I lived in a country once that lost most of the forests in the 1960-70's and still if holding out on offers from large paper companies to come and cut down the rest of the forests. I have a blog dedicated to Spiritual issues and to the discussion of theology. You are invited to visit and comment.
