Old wordpress websites need editing

I have several live eCommerce websites which need to be given a new face. Most of the content is not seo friendly and needs to be removed and I will provide new content to be added (about 50 articles and over 200 word files as samples in the samples page). I will need to be given alternative design plans to choose from. Bid only for only 1 website. -Website Designing Consultation -Branding Development Consultation -Create a text Sitemap -Google and Msn analytics to be added. -Metatags to be added. -Delete unneccessary existing content. -Add major search engines webmaster tools -Correct w3c coding error validation, there are many in the websites and these errors create hindrances in the search engine crawling through the websites. -W3C validation for Homepage -Site changes implementation -Google XML sitemaps -Log File Analysis Any related activity NB: These websites are live and have clients placing orders every other-day so no interference with the site functionality please. I will set milestones as we shall agree BUT the milestones will be released after project completion and certification after verification by my IT guys. Thanks
