Content Article For Website

Hello I am looking for a content article written on lawn tractors. The article needs to be around 600 words in length. The single keyword phrase that I want you to focus on is, "Best Lawn Tractors" So I want the keyword in the title, in the first paragraph and then a 3% to4% keyword density throughout the rest of the article. This is an easy job for someone who knows what they are doing, it will require you to do your own research and analasis if you win this job. If you write me a good article, I will give you more work in the future. All work will be tested through Copyscape premium for uniqueness. Regards Philip
