Here's the deal. This is a long-term project.
I need excellent English writers to re-write articles. You get paid by the paragraph.
Some paragraphs are only 2 sentences long, others are 4 or longer. You get paid the same regardless of how short it is.
For starters, I'll send you 10 paragraphs and pay 20 cents per paragraph. If you meet the deadline and your works is good, with perfect spelling (using spell-checker), good grammar, and passes Copyscape, then I'll send you 50 more and pay you 30 cents per paragraph. If your work is still good, you'll get as much work as you can handle and your pay will go up again to 40 cents per paragraph.
My best re-writers are making more than $100 per day.
