Hello barrie wilkins,
For your articles I will implement all the seo friendly keywords to get them seen from the search engines. Main priority is to get the articles done in time frame of 4-5 days so I can write them, do some editing, and send you the 20 articles. $10 an article work ?
I am professional writer/seo analyst that helps clients reach well with their blogs and web articles for past 3 years. I can send you sample of kind of article writing i can do.
