237953 Search Engine Optimization

We are currently in need of SEO skills to help boost/drive traffic to our website. We are looking for experienced persons that know how to modify our metatags (We use PHP code) to move our website to the top of the major search engines. Please provide any experience with proven results in your bids for SEO and back links. We hired someone before that did the work required for link exchange and article submissions, but this did not really help our rankings. We need someone that can work on our website design and keywords to remove code that hurts us and add keywords in a graphically pleasing way that will help us.
