Article Rewriter (with or without software)

I am looking for an individual who can help me with rewriting an article into 5 variations. Preferably, contractors who have their rewriting software are needed since I needed the task to be finished in an hour. I will only hire a contractor who can show me proofs of rewritten documents which are still readable without the crappy and unrelated words usually caused by poor rewritten article by a poor software. Each rewritten article will cost 0.50 dollars. I will assign 2 articles to be rewritten which can will sum up to 5 dollars for 2 articles. I need to finish 150+ articles to be rewritten into 5 variations each. Thank you.
