Article writer with proper knowledge of keyword using

I need some articles, roughly around 8-10 per day. The article size will be of 200-250 words each. The articles will be keyword based. I will provide you with many keywords using which you have to write articles every day. I will inform you how to use them. The articles should be error free. And they should be completely original, i.e. they should pass copyscape. I will provide you a keyword for sample and you have to write an article within 3 hrs so that I may choose the most appropriate person. I will pay 0.5$ for every 250 words article if chosen. Plz bid if you agree to the above requirements. Only serious writers needed. Freshers are also welcome.
