Code Clean-up, Menu Creation, Dynamic Pages & SEO

Hi, We are a Heat Exchanger manufacturer’s representative, selling heat transfer equipment for the industrial market. I, work in sales and marketing; I developed the current website that represents our company. We are looking for an individual or company that can provide us the following: 1) Optimize our HTML / CSS structure, cleaning up the code that I poorly wrote over months and years. While I consider our site the best in the industry, I feel there is room to grow and improve. Specifically I’m looking for the site to work across the most common platforms, screen resolutions and internet connections. 2) Improve our menu ‘slightly’. We like what we have, we want it to me a bit more interactive, load quicker, and should be dynamic enough that on different pages the submenu shows different information; yet it all should run from the template page. (eg I don’t have to manually make changes like I do now to every page if the menu changes) 3) Our site has a fairly good GOOGLE / BING / YAHOO rank, however it could be improved upon in various areas. I’m not looking for sleazy SEO tactics; everything must adhere to Google policies. Designer should provide references of successful work completed. 4) We feature a lot of different products on our websites. These products include specs and related information. They are not purchasable ONLINE, however we would like an easier way to list and feature them using dynamic pages in certain parts of our site. 5) Integration with DREAMWERVER / FIREWORKS is a MUST. This is a onetime project; I must be able to edit and configure the site on my own into the future. No special code / etc. OPTIONAL: We don’t want to sell ONLINE with shopping carts for the most part. We have one or two product lines that could be sold online in a shopping cart setup; we would like to use Google check out or something similar. Were open to ideas. our sites: [login to view URL] Please dont bug us if your not interested or your going to try to sell us something we dont want.
