You ought to read the book by Eric Gibson: Sell what you sow, and other books by him. He is expert on marketing. I got some of the material in the Marketing Chapter of my own book, ORGANIC METHOD PRIMER UPDATE, from his work. You might see if your local library would buy my book, as it surely will have at least something in it that would be useful. It is the most comprehensive book in the world, on the subject. B. Rateaver
