Original Articles regarding MS Excel

Hi All, I would like around 10 original articles to be written based on keywords I will provide around the subject of Ms Excel. In each article I would like the keyword or phrase to be mentioned twice. I am looking for a good article writer as I am going to be using their services going forward quite a bit. NOTE: I DO NOT WANT SCRAPED TOGETHER CRAP FROM THE INTERNET. I will check each article via the internet to see if it is plagurised and only when I am happy I will release payment. For the right article writer, they will recieve a vast amount of work from myself over the next 12-18 months. To ensure I dont accept a robot bid can you please include "I UNDERSTAND EXCEL ARTICLES" as your first line in your response. Thank you for your bid.
