Article writers required urgently

I am looking for high quality writers to rewrite articles for an ongoing project. It must be rewritten by a native English speaking writer. I have a number of articles to be rewritten. I pay $1.00 per 500 words and will increase it with proven reliability and writing skills. I do not accept bidders that requires me to pay partly in advance, as some people do not deliver the project after I made an advance payment. Passing of Copyscape, Dupecop and Plagarism etc detect is compulsory. The rewritten article should be 100% unique. I pay via Paypal within 24 hours of completion of each project, so the sooner you can finish the article the sooner you will receive payment. The articles need to be informative to the reader with 100% correct grammar and punctuation. You agree that upon sending me the rewrites all rights to the rewritten articles transfer to me. This means you will not sell, reproduce or re-use these articles in any way. I will hold these articles for a random period of time, between two weeks and one month before checking for duplicates, as I have had issues before where writers submitted the same article to multiple jobs. Bids will only be considered with a sample article on a topic that I choose. Please type this in your private message (PM) to me. "I understand what to do" so I know you read and understand the requirements. I have attached a sample paragraph, please rewrite the sample paragraph and send it to me. Only bidders who submit the sample rewrites will be shortlisted. Thank you and I look forward to hearing from you .
