E book publishing

I'm looking for someone to help me create an e-book that's more than 100 pages long, of non-fiction content and based on a clear idea I have in mind. The chosen freelancer will be responsible for helping me bring my idea to life by researching, drafting, and editing the project until it meets my standards. The ebook should be written concisely and engagingly, while still conveying the necessary information, and in a way that resonates with my target audience. Lastly, I am looking for someone who can deliver the project in a prompt and professional manner.
