Professionally Rewrite 9 Articles 10X Each

This project will be for professional quality article rewriting. I have 9 articles that will each be roughly 700 words. I need each article rewritten 10X. Each rewrite needs to be unique (50-60%). You can shorten the articles (min. 300words) or lengthen the articles (no max) to achieve this as well as paraphrasing, etc. No more than 3 of the rewrites can be at the minimum. Another 3-4 at around 500 words, the rest at or near current length or greater. Final article rewrites must read smoothly (no machine spinners). All article rewrites will be proofread so they must be rewritten well, smoothly, and 100% grammatically correct.
