Review retailers or brand name products: Auto Tires

I have a list of about 20 retail tire outlets, tire brands or accessories which I require reviewed to produce useful and informative articles for persons who might be shopping for these items or considering these brands. The articles will be aproximately 1000 words in length and need to be keyword optimized according to the subject. I will provide some sample articles on other topics to illustrate the kind of approaches which might be taken when the successful bidder is chosen. My preference for this project is to work with a writer who is familiar with vehicles, but not from an overly technical point of view. I wish to see some sample product-review type of artices that you've done previously to help choose the most suitable bidder. I would like you to bid on a package of 20 articles, with the understanding that we may have to adjust the size of the list up or down between 15 and 25 on a pro-rated basis since some of the possible topics may not pan out. I will require the articles to be delivered in html format with suggested sub-headings and links to relevant official sites and/or in depth sources. Project to be completed within 2 weeks of assignment. All text needs to be original, spell checked and using excellent US English.
