Articles Written with App Keywords

Native English speakers only. If I accept your bid and you're not a native english speaker and I get the article with lots of grammatical errors because you obviously don't speak english then you won't get paid. No exceptions! I need to get 15 articles written for keywords that relate to iphone apps and ipad apps. I will give you the set of keywords. I want the articles to be written in a bullet point format or numbered format such as 5 reasons....or 7 facts about ..... They should be 550-800 word articles.
