Hello, my name is Edith, I'm from Latin America and a Spanish native speaker.
I've worked as a columnist for a local magazine (so I have a very good grammar and spelling) and I have a couple of books being outlined for future publication, which it's why I think I'm perfect for this job.
Depending on your needs, I think a good time to have the job done is 30 days at most. The first week would be nothing but outlining of the story, and the two next weeks would be writing and nothing more. The last week would be detailing and correcting the text. We'll communicate daily for the first two weeks, and then, every three days. Also, it all depends on how much long the book will be. With more data, I could make it in less time.
Many others are bidding for this job being done in 10 days. But, let's be realistic: It won't be a quality job. I'd rather being honest and give you realistic expectations that we can beat instead of needing to delay the work. Also, it's better take time to do something good than hurry into something mediocre.
Hoping to work together.
