Need 15 articles!

I need 15 articles created. The main purpose is to have them ranked for their keywords in the search engines. And ranked well. Keyword phrases will be provided. You need to have a good understanding of the following. . 1) Keyword density - What is it? What's the optimal amount? Where's the best place to put the keywords? Please PM me with your answers. 2) Write engaging stuff - Headlines, intro paragraph...EVERYTHING!. Your articles need to be interesting, easy to understand, and will have readers read completely!! I need to HEAR YOU the person talking. Does that make sense? If not, then this aint the project for you. I'd rather have interesting articles that provide just enough value than info overloaded boring articles. I like numerated articles (ie... "5 secrets to blah blah") with quick bites of information...3-5 sentences per paragraph(this information alone with help YOU become a better and more effective article writer). 350-500 words. I need 2-3 day turnaround. Please give me at least 2 articles that you have written. Thanks
