Hi, my bid for the 40 articles, of 350 words each on the referenced topics, to be completed in 10 days, for $150.00. I have written on these topics before, as well as I have experience in article writing, copy writing, blogs, SEO content, keyword density/optimization, news letters, reviews, summaries, descriptions, ebooks, web content, and reports. I can complete this project for you to your specifications and I can start ASAP. Thanks!
