Fitness and Health Article Rewriting

I need a freelance writer (Native English writer) to do 50 fitness articles rewrites. Articles must be 100% free of all kinds of grammatical and spelling mistakes. Articles must be 100% plagiarism free and pass CopyScape. All articles must have tags as well, do not bid if you cannot handle the workload. All these articles must be completed within 15 days or less but you must send at least 3 articles a day. I will pay $40 for the 50 article rewrites. No more, no lees so do not bid higher than $40. Thanks in advance.
