Required Article Writing,Blog Writing freelancer for English texts re-wordings. job

I need to hire someone for re-wording of already existing text in American English. The texts need to be re-worded in American (preferable) or British English in a concise form of Encyclopedia style. The texts will be very short but I will send them rather often - for at least 3 times a week. This is a very long term project on a weekly basis and will not take much of your time. The texts are from 200 to 2000 words at the maximum.
Please, suggest your rate per 100/1000 words for proofreading, grammar editing and re-wording(most often). I put the budget deliberately but it will be different each time.
Please, be aware that you will be required to prove your fluency in English by showing your proven reviews and portfolio on Toogit or (if you lack one) to be ready to re-words 4-5 lines of any text for my evaluation. I need to hire people for long term and I need reliable freelancers with great knowledge of English Grammar and writing skills.
