Hello,
The project looks very interesting to me. I would like to have a go at it.
Here are some further points that I think will help clarity:
1. Will you like it in format of ebook or as articles or blog posts?
2. It would be great if you can freeze the titles of the different chapters. This will become the ToC (Table of Contents) for the work, and we can both measure the output with the ToC.
3. Are you also looking to embellish the book with stock images which readers find easy to relate to and make the running black-and-white content less monotonous? This can be arranged from the license-free public internet.
After receiving your inputs on the above, I shall be in a position to calculate the bid estimate.
Regards,
IBArena
