Hi! My bid currently is for a 200-page book (roughly 80k words, in my experience) to be developed jointly based on your outlines, data, and ideas and my implementation of those outlines, data, and ideas. I've ghostwritten and edited dozens of now-published books, and would love to do the same for you.
My timeline is longer than many other bidders, I realize, but as you note, it takes time to ensure we do this right. After we've talked further, we can develop intermediate milestones based on the successful completion of each chapter and the finalized manuscript; I know I prefer having those checkpoints to help ensure we're on the same page, and I'd imagine you would as well.
Please reach out so we can discuss further. I'm happy to answer any questions you might have and share relevant samples of previous work. Thanks much for your time and consideration, and I look forward to hopefully talking more soon!
