write an ebook on omega 3

I require an ebook to be written on the importance of Omega 3. The book should provide an introduction to Omega 3, explain EPA, DHA ALA. Explain the importance of taking it. Explain the dangers of not taking it. Explain fish oil extraction. Explain the dangers of fish oil. Explain the option of natural plant-based Omega 3. Explain how plant-based is mainly ALA. Explain how breast milk also contains ALA. Explain about flax. Explain downsides of flax-based omega 3. Explain sage-based omega 3. Explain particular product I'm selling on sage-based Omega 3. Explain other natural components found in sage oil. Explain how to get sage-based omega 3. Conclude. The book's primary purpose is to sell the sage-based omega 3 that I'm offering, BUT it needs to be an informational book, not salesy or hypey (until the very end, at least) Target readers will be people with no knowledge of Omega 3 or small knowledge of Omega 3, and the book must convey Omega 3 as being critical for any healthy life (there's plenty of scientific data to support that claim without sales hype). Previous experience with writing informational products as a pre-sale will be a huge extra. Please provide samples of your previous writing and at least one paragraph of content that could be used in this book with your bid so I'm familiar with your writing style in advance.
