Hi, my name is Matt and am a former technical writer (Doc-To-Help Certified Trainer).
Can you please provide more details about the topics and the (interactive?) ebook for your project?
For the topics I predict you mean some modern environmental issues like environmental sustainability, the quality of life, recycling water (surface water management for cities), global warming impacts, waste re-usage etc.
Regarding the ebook I can create PDF, Mobi and Epub 3 ebook formats yet also implement (Apple) iBooks interactive book.
Either way I predict one focused week of research is needed when we establish and confirm topics and subtopics. I still have access to ProQuest and Emerald online academic databases (of science papers, mainly social sciences) that would suffice with searching some natural sciences academic sources by visiting a national library 50 miles away.
After that a writing phase with ebook in mind would follow and final editing, proofreading and ebook creation would be last.
Yes, the motivation is the amount available yet I'd like to create a reference project for me. Recently I have written a shorter paper on FoxConn issues with - bad - work conditions in their factories (where Apple iPad and other devices are manufactured) and am generally interested to visit Hong Kong and China one day.
Looking forward to receive more information from you,
Matt
