Appreciate the further consideration of those points. As for your project; do it! If it'll help people, write it all and release it under a creative commons licence. Spread it far and wide. It could be your legacy, long after you've left the earth and stopped worrying about money. I self-published a book in 2011. I charged for it. It ran its course, the product lifecycle played out and I'd made more than it cost to put it together. It's now free to read on my site and will soon be added to the creative commons as a PDF to be freely shared. I continue to benefit from its existence in other ways than monetary. If you really do want money in return for the effort, charge for the publication. Get it published professionally or self-publish and promote it widely. Do you think the ad model is best because you are convinced people will only find what they're looking for through a search engine or social media? EDIT: Would the people you help with your publication be helped even more by the ads displayed alongside it? Who would click the ads to make the project pay?
