Hi, Marco. Whether or not I work on improving your English text, I will be happy to see your book published. I enjoyed reading the sample pages, and believe it will help other people, too. But let´s get down to business. I´m American, living in Brazil, a native English speaker with lots of writing and editing experience. I work mostly with Brazilian university graduates (non-native English speakers) who wish to publish their academic work abroad for an English-speaking public. These texts have a much "drier" style than the samples of your writing. In regard to your sample text, I enjoyed your style and can correct the wording without interfering. About the delivery deadline, I have learned over the years that less stress and urgency is healthier and usually leads to better quality production (sort of like your rule for Day 247), so I work slower than the current social pressure demands, and listen more to my "inner voice" or whatever you want to call it, which I can hear more clearly when I´m not so beat. I would like to take a month for doing this job, but what are your time requirements? Also, I would like to know what are the words at the end of each Day´s text - SEO keywords? Some kind of reference? How do you want them treated? Please contact me with more information, I really would love to work with you on this.
