As an American conservative who has long been a political junkie (my interest in politics began with Nixon's 1972 re-election campaign), I was extremely interested when I saw your book's title. Granted, political inclinations will probably not be the deciding factor for you as you choose a writer for your project, but mine should at least provide you with some idea as to the level of passion I would bring to such a venture.
My writing ability can be seen from the sample pages in my portfolio - one of which was for an eBook (not political, but useful as a sample of my ability to organize themes within cohesive chapters while maintaining the book's overall flow).
Your parameters, and my understanding of them:
40 pages (I am estimating this at around 20-25,000 words. Is that what you had in mind?)
* Show how she moved her way up to become a frontrunner in 2016 (Would that include her history dating back to her first run for the Senate, and the Clintons' de facto shadow government within the Democratic Party? I also see her 2008 run and subsequent participation in the Obama administration as helping her to remain the go-to Democrat option for '16)
* Cover the good rumors/failures (the failures are many. You might have to clarify what you mean by "good rumors" though)
In any event, if you want an easy to read, well-written chronicle and commentary on the political creature that is Hillary Clinton, I have every confidence that I can provide you with what you need
