Hello,
I'm a professional freelance writer, and a native English speaker. Your project sounds exciting, and at a rate of 2000 words a day, we have ample time to complete it - I'm sure we could get it done within 20/25 days. How soon would you need the first 10,000 words?
I am ready and willing to work on your project, and at the moment I don't have any other major obligations - I can devote myself entirely to the book. However, I would need a rough guideline for the book, obviously - even better would be a rough chapter outline - one line to indicate what you expect from each chapter would be fine. If the story arc is still incomplete, that's alright, but in that case I will need you to be available to give me feedback when I send you progress updates, to make sure we're on the same page.
If you hire me, I can get to work right away - let me know. I look forward to talking to you about this further. For now, why don't you send me a writing prompt and I'll give you a sample? That way you'll have a good idea of what to expect.
All the best,
Conor Maloney
