It is not clear to me how many articles you want us to bid on, so I'm having to make some guesses. If I'm way off, please let me know and I will re-submit my bid.
My assumption is that you will need 30 articles rewritten at $10 each over a period of five days. My bid may be high, but I have no idea what the subject matter of the articles is and how long they are and how badly/well written they are, all of which impacts the time and cost of the work to be done. I am a skilled, experienced writer and would like -- for both our sakes -- to get one sample article to rewrite for you FREE OF CHARGE as a test case.
Thank you.
