articles needed - bulk quantity

Hello, We are currently registering different domains about different topics. We need approx 10 articles for each of our domains and each article should be at least 500 to 600 words. This is a long term project and we are looking to use the vendor for at least 500 articles to begin with. But we need the cheapest prices for the articles, we won't be considering high prices. Please do not post your long introductory letters via PMB. Just send your price and a couple of sample articles references. Thank you
