SEO expert needed

A recently completed online directory website is in need of comprehensive Search Engine Optimization (SEO). For this project, we need an expert specializing in this area to review, analize and optimize the site. For this project (phase 1 of the SEO) you do not need to do any link building, just the actual optimization of the pages. I'll be submitting another project later on GAF for the link building part. We insist on ethical techniques only… any unethical techniques will not be tolerated. We are managing numerous websites, and if we are happy we'll give more projects and consider a long-term working relationship.
