Need 500 articles

Hi I need someone with a big team of copywriters who can turn out 30-60 articles a day... Articles are very general in nature and around 400 words each... Keyword density followed should be around 4-5%... I need the articles urgently and thats why I need only those bidders who can do this for me... Those who can't do it pls don't waste time in bidding... Pls attach a sample of around 200 words on "weight lifting"... I am looking to pay around $2 per article. Though depending upon quality and time of delivery, prices can be negotiated... Thanks
