SEO Expert Needed

I am not looking for someone who knows all the dirty tricks to get ranking, but someone really professional with great experience in SEO. I have website(s) with over 500,000 pages. Each page has product information and this information is provided to us from sources that are giving it away to other people as well. So chances are that the content is duplicate and used on other well established website(s). I want someone to plan a campaign for SEO and suggest each step that we can take to get organic traffic from search engines. The overall goal is to get relevant traffic and build an online credibility of the site despite it's duplicate content. When I say duplicate content, I am not talking about articles, images, etc but product description, specs, product images, price, etc. For this bid I will consider bidders who can show me their successful projects and also tell me a little bit about the best way to attack this situation. This will be a long term relationship with the right person. Thanks in advance for taking the time to read this request. ## Deliverables Please do not ask for URL of the website. It is a brand new domain name (registered yesterday) and has the category keyword. The products sold on this site will be related to sports and associated with various teams across the US (Giants, Mets, etc). I need someone really professional who understands the best way to approach SEO for such projects.
