Imtech - Web site update

This project involves updating and modernising my company web site. The web site is very basic, and I would like to have it updated to reflect a modern image. However, I would also like to maintain the web site in house once the new layout has been created. I do not want a fancy flash presentation at start up, just a proffessional looking web site that functions quickly. We have limited knowledge of Dreamweaver - the program used to create the current web site. I look forward to receiving bids from interested parties.
