Seo & Web Marketing Promotion

I am looking for an established company or individual to work on my gambling portal site to take it to the next level. I am only looking for bidders that have excellent feedback and a portfolio. Job will include -analyize and fix any seo issues, link building, directory submissions, fix any coding issues, just to name a few. Because I am the novice Seo, I am looking for someone who really knows what they are doing who will know exactly what my site needs to take it to the next level. I built the site in Dreamweaver and read the basics on Seo, but because I am the novice I know the site needs to be touched up in many aspects. I have many big projects on the come, and I am really hoping to find a company or individual who I can continue a business relationship with. I will only work with someone who applies ethical methods to gain rankings. Please no blackhat or tricks.
