Website Refresh

We run a website in Australia that sells projectors. It runs on the Joomla CMS. Though the website looks very good, it seems it is very hard for users to navigate and find products they are looking for. The way that items are displayed is also clunky. There is a simple navigation menu on the side of the screen and product listings contain plenty of information without having to open the item up. Sale items also have an animated gif making it extremely easy to see specials and attracts customers.

We have spent money already focusing on SEO keywords and we do not want to loose out SEO rating, therefore if you can not gurantee that the keywords will still rank us high please let me know. All short listed proposals will be passed by our SEO partner to make before we choose the winning bid.
