SEO on Paintball

I wanted to repost this project due to a lack of detail in my other project. BEFORE YOU READ: If you do well writing these articles, you WILL be hired to write more articles for me (assuming you want to ) :) What i want is 5 paintball-related articles written that can be easily read by human eyes as well as search engines. THESE ARE TRIAL ARTICLES. I will want a part time article writer. No beginner writers DO NOT BID UNLESS YOU FAMILIAR WITH THE IMPORTANCE OF SEO ARTICLES - INLCUDING KEYWORD DENSITY, IMPORTANCE OF KEYWORDS, AND OVERALL OPTIMIZATION. Please keep in mind that I am not SEO illiterate AT ALL. I myself have extensive knowledge concerncing SEO and websites. I could do this myself, but I just don't have the time. I will say again... no beginners please. You're english must be ... well english. I want articles easily read by the ages 12-30 year olds. I am not looking for profound articles here... I'm looking for easy-to-read informational articles. You must have at least some experience with the sport of paintball. Or at least you must first research the sport extensively. Like I said I know how to do most of this but I have no time really. The articles will cover the following: - Cheating in Paintball Games - History of Paintball - What is paintball (how to play) - Airsoft vs. paintball - Paintball safety Articles should be AT LEAST 500-600 words. I will be sure to take effort into consideration for future work. Keyword density should be around 4% plus or minus. Again, i want the articles optimized for search engines, but I don't want the articles written like they're for the search engines. Good seo writers should know how to do this fairly well. Any questions are welcome. I'm willing to pay promptly right away.
