Hi,
My bid is $5/500 words.
I have a team that can handle 10 a day. But if you will award me this project, I can acquire more writer so we can finish more than 10 a day. For a detailed view, here's how I operate:
1. Operating Days - 7 days a week
2. I have copyscape to check originality.
3. As much as possible I do not allow my writers to write more than 10 a day in order not to compromise quality.
