Webshop writing on blog and article sites

We need 60 separate articles for our e-commerce business website, which each need to be optimized / re-written for each article site. This is a job, spread over 10 weeks, where we need 6 articles per week for our own blog, and 3 re-written versions and be posted on different article sites. So when you create one article, then you need to be optimized / re-written for each of the 3 articles sites. We have as budget; $10 per written article + 3 times re-written articles. So in total of 60 x 3 (re-written) separate articles we have as budget $600. This is a hourly job. When interested add in your offer "i can write". To see if you have read my project description in detail. Basically you only need to write 60 articles, with high quality images and proper presentation (400 upto 500 words each). And each article has to be 3 times re-written for other sites, this means the Title, Headings, Text-construction, Text-usage, and Image names has to be different per re-written article.
