Personal Development Book Proofreader and Content Editor

For a joint book project, we are seeking a proofreader and content editor to scrutinize every detail of our personal development book. Since English is not our native language, we need help with grammar and spelling as well as choice of words. Furthermore, we are struggling a little bit with the perspective, that is, the way to address the reader. Sometimes we are not sure whether it would be better to use "we" or "you". Besides that, the editor should also review consistency and logic when it comes to the content of the book. So actually, it is the "full program". An English native speaker with strong attention to detail and experience in proofreading non-fiction work would be ideal for this task. We would appreciate the freelancer having a keen interest in personal development genre and being open to ideas that go beyond mainstream. Let's create a flawless masterpiece together!
