5/10 articles per day for 1 year

We want freelancers to write articles of about 400 words. The articles may be about health, lifestyle, society or any other topic. The articles should be original with no copying allowed. The content can be collected from net after careful research but all the wordings should be original, pass copyscape and be unique, written in proper English without any mistakes in spelling and grammar. The articles would be tested for plagiarism and if any line is found to be copied/lifted than project will be cancelled without payment for that article. All articles must be keyword based and correctly optimized with good keywords density. The articles should be informative. All articles should be SEO based. We require at least 5-10 articles per day. If you can attempt 5 articles per day, then post your bid for 5, if you are comfortable with 10 per day, then bid for 10 articles per day. The payment would be 1$ for every two articles or 2.5$/5$ everyday amounting to 75$/150$ per month depending upon the project chosen(5/10 articles per day). It is an ongoing project and not few articles for few days. You would be given list of 35/70 articles for week's work, and you have to submit 5/10 articles every day before 16.30 GMT. The payment would be made on weekly basis. After the receipt of first day's work , the articles would be tested and if found original, payment for 1 week including 1st day's work would be deposited in an escrow account. We would own the copyright and all rights to the work. You may not publish the work in any way. Please do not apply unless you agree to this condition. On this project I cant offer more as I am getting only 1$ per article. But as and when I get other better paying jobs I would pass it along. I have many projects with 1$ per article and even 1.5$ per article which I have passed to my selected service providers. My association would be long-term and fruitful as I guarantee fast payment and sure income in this uncertain world.
