I am almost finished with writing a book about email management. I have chosen for US english. Since I'm not native english, I am looking for a proofreader / editor to improve the reading, make adjustments and check for consistency (US/UK spelling).
I can deliver the book in .EPUB or PDF format, please tell me what you prefer. I would like to be able to see the changes that you make, so I can learn from this for future writing. If you need much more than 10 hours, please inform me.
