Use the keyword 4 to 5 times throughout the article.

The article should be 100% unique and of your own work, it will have to pass copyscape and be of premium quality.

This is a trail for a larger job of 80 articles, I will be submitting your article to a client and if they like it I will be able to offer you the job hopefully, so make a good one. I will pay £8 for this article as a one off, then if my client wants to go ahead I will let you know a fixed price for the job.
