Ajax Search Autosuggest

**Search Box Auto Auggest in Ajax** I am looking for a coder to do the following simple function; There is a search box already working, however I would like something like google where an auto suggest comes up. As a user types the first letter there will be 10 suggestions and as the users types more letters it will find a more suitable suggestion, I want it so the user is able to click on the suggestion and will continue to the search page (already designed)
