Ghostwriter for business book in English

I am writing a book on the how technology trends will change healthcare. The book will describe the new technologies (e.g. Virtual Reality), what currently is happening (e.g. Venture Capital investments, start-up) and how the technology might be used in the future in health care. In total I want to cover 10-15 key technologies. Solid research of the web will be required to capture current trends looking at news articles, blog posts, web sites, press releases. Total length of the book 150-200 pages. Job ideally freelance but can also be full-time. Applicants need to be proficient in English professional writing. Ideally also understand a bit technology and healthcare, but more important to be a great writer and independent researcher.
