Reliable low rate writers ( native Eng. Please )

Hello. I need a reliable native English writer for an ongoing project. The topics are all about news and review of new tech. articles. I am willing to pay 0.5$ for the first 100 article, approx 400-500 words. The articles need to be unique and pass copyscape. The grammar and punctuation will be checked as well. If the article does not pass copyscape or have many typing or grammar errors I will not pay for it and the project will be canceled. I am looking for a long term provider who is ready for some serious project in the future. The rate will be higher after the first 100 article. If I am satisfied there will be 200-300 article per month with higher rate. Please only serious providers should apply. Kind Regards Dominik
