Convert fairly simple HTML tabled based website to CSS

I am interested in converting my website ([login to view URL]) from an HTML table based site to a CSS only site. I've made some fruitless attempts at getting this accomplished and would like some assistance. My results were inconsistent across various browsers. The CSS coded site should closely resemble the site currently online as viewed under Firefox 1.0 . The CSS coded site should look basically the same under Firefox, IE, and Opera. The logo/header portion of the page should be 800pixels wide and be centered regardless of resolution (>800pixels). The main section should be 100% of the browser width with sidebars on the left and right. The same simple footer should remain, but either at the bottom of the viewport or at the bottom of the page depending on amount of text in the main section. The images, html, and current CSS can be downloaded directly from the website, or emailed if necessary. ## Deliverables 1) Complete and fully-functional external CSS 2) Sample HTML file using fully-functional external CSS to position website elements based on current layout of [login to view URL] All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform Site must render virtually the same in Firefox, IE, and Opera webbrowsers
