Writing books

I'm looking to publish a biography book that I have in mind. It has been an idea of mine for some time, but I need help fleshing it out and bringing it to life. I already have a specific target audience in mind – people who already know and understand the subject of the book. The approximate length of the book will be around 10,000 words, so it will be a short story. Therefore, I am looking for someone to take my ideas and turn them into a finished product. If you have any experience writing books or biographies, I would love to hear from you. The ideal freelancer for this project should have strong writing skills and attention to detail. The end goal is to create a book that accurately portrays my ideas and represents the subject in a way that readers can relate to.
