60 short, game promoting texts with keyword density

I am promoting a text based online game by creating several landing pages for specific keyword phrases in google. I need someone that know how to write articles that capture the readers interest and make them want to sign up to play a new an exciting online game. The target audience is mostly boys under the age of 20. It's important that the writing appeal to this audience. Each text only needs to be around 300 words. The articles should be written following this guidelines: I will provide a keyword phrase that needs to be repeated in the title, the first sentence and a couple of times throughout the article. (keyword density, google it) - Needs to be 100% original articles (copyscape passed) - I maintain exclusive right to the content - No grammatical mistakes - Appeal to target audience I provided an example of similar games and their "sign up now" texts. (They do not include any keyword phrases). All copyright to the work belongs to me after payment, and you are not allowed to resell/reuse it. A sample of your work will be appreciated.
