Hello,
I'm an English native, an expert writer, and an excellent editor.
If hired, the first thing I would ask you is why you want to write a book? Second is, who is your target audience. Third is, what is your objective? Your answers to these questions would help me guide you on how to make your scattered thoughts a book that would anyone who reads it awed.
I am available to start immediately, and if hired, I would do an amazing job.
I look forward to hearing back from you.
Thank you.
