re-writing 20 articles

I have a simple re-write task for you. I have 18-20 articles that need to be re-written. keep in mind while bidding that re-writing does not mean changing synonyms and presenting the work back to me. the rewritten articles should make complete sense. I am willing to offer $1.5 per 500 words to the winning bidder. You shall be paid as soon as the work is complete, or even for half of the articles as soon as i check that they are ok. Your work should be copyscape free/dupefree. The re-written articles should be of the same word count as the original articles. Bidders to send their bids, as I want to get started right away. Future work assured for those who perform well
