I am very experienced in Online Marketing and can easily surpass your expectations. Not only with the content of the news releases, but with the amount of sites that will publish the articles.
Plus, each article will contain two links that link-back to your domain; this will cause your site to have thousands of in-bound links, which will greatly increase your search engine ranking.
If you're interested, I can supply you with a list of references. I look forward to working with you.
