article writer in english

I am looking for one or more writer/writers for writing fresh content for various projects. I need 200 articles, 500 words each. You can bid as long as your English is fine. I do not want people who do not write English well, so those who are not confident about their skills, do not bid! My maximum rate is $1 for each article (500 words). I want only those article writers, who can give me quality, plagiarism free and error free articles. Please understand, that I am very concerned about the quality, so if you do not have perfect English, please do not take the pains of bidding. Looking forward to receiving quality bids. Do not bid above $200; your bid would be ignored! Please bid only if 1) You are absolutely fluent in English 2)Know what content writing is (plagiarism, importance of timely delivery, keywords usage etc.) All the articles submitted should be copyscape passed Articles must be seo optimised. Use the keywords that will be provided in title and across the article. I will ask you to write a sample article for some keyword before accepting the bid. We would retain the right of all the articles and samples provided to us. You can't use them anywhere else.
