Article Rewriter required - 50 rewrites per week (10 a day)

Hi, I am looking for high quality writers to rewrite articles on a regular basis. I will supply you with all of the articles to be rewritten as well as all keyword phrases on a daily basis. I will need a minimum of 10 articles submitted for my approval from each rewriter PER DAY for a total of 50 articles submitted per week from each rewriter. I require 10 rewrites to be submitted to me within a 24 hour period of me emailing you the articles and a minimum of 50 submitted a week (so that will be 10 articles a day, 5 days a week). All articles must be written by a NATIVE ENGLISH SPEAKING writer. The rewriting will need to be concise and to the point. The articles are actually intended to be read and not just to fill up space or increase keyword density so please do not bid if you cannot speak perfect English. I can't accept articles just filled with fluff words meant to fill space. I pay $1.00 to start per 400 word article (I always require a minimum of 400 words, and anything above that is fine) and will increase it with proven reliability and writing skills. Therefore at the start you will be earning a minimum of $10 a day, and $50 a week. Furthermore, after working well for a few weeks additional projects will also be offered that could pay anything between $1 and $15 depending on the requirement. The keywords I provide you need to be used in a normal and conversational way throughout the articles please. The keyword/keyword phrase needs to be in the article title, first sentence and used another 10-12 times throughout the article for a total keyword density of 2-2.5%. I will send you a free piece of software called DupeFreePRO in case you aren't familiar with it. This software allows you to quickly and easily check your keyword density. The articles need to be informative to the reader with 100% correct grammar and punctuation. Also, the articles must be fully unique, they will be reviewed through Copyscape and Plagiarism Detect for plagiarism. Please note I am not asking for fresh material, but rewritten material; so although it must not be copied, you just write the original article in your own words. If an article you submit to me does not pass Copyscape or has spelling and punctuation mistakes, you will not be paid for that article until it is corrected and resubmitted to me for approval. I pay within 24 hours of completion of each 50 article, so the sooner you can finish the articles the sooner you will receive payment. To clarify, you will be paid $50 after a batch of 50 articles (therefore $50 weekly). When I hire a new writer I pay them $10 at completion of the first 10 article batch to show that I pay, and then at the end of the week I will pay $40 for the other 40 articles, after this, the full amount will just be paid at the end of the batch of 50. You agree that upon sending me the rewrites all rights to the rewritten articles transfer to me. This means you will not sell, reproduce or re-use these articles in any way. Please be able to communicate 1-2 times per day via email or messenger. Bids will only be considered with a roughly 400 word sample article on a topic that I choose. There is no need to send me your own sample, and if you do so I shall take it as a sign that you have not read this fully and will therefore not be contacting you! After bidding please PM me confirming that you have read, understand, and accept the requirements in this listing and I will then send you a sample topic. Thank you and I look forward to hearing from you. PS. Please note I have put the budget as $50, but this is actually the minimum weekly pay and the earning potential for this is actually much higher!
