Change content based on location...

Hi.. I want someone to write a code for me that allows me to change part of the web page, based on visitor's location... So based on the IP address (I already have the database of IPs for cities/countries). What I want is to print something on the webpage saying something: " Hi visitor, we know that you're from the city of Tallahassee, which is in the state of Florida" The website is *.html ... I can rename it to *.shtml and we may use server side include (SSI). I don't want to change this to a PHP site. Should be a simple code, I'm already researching this :) Thanks, Mary
