Create Javascript That Converts Keywords Into Amazon Link (GEO)

I'm looking for a Javascript Expert who can write a FAST script to turn keywords on a webpage like "Batman", "Superman", "Guild Wars" into clickable links to the correct amazon page for the visitor and the country he resides in. In short: 1 Analyze a webpage for keywords - keywords are stored in a text file or whatever you think will be FASTER 2 Retrieve a PHP variable $_SERVER['GEOIP_COUNTRY_CODE'] and store it via javascript 3 Dynamically re-write the keyword from (1) to a clickable link leading to the correct Amazon page based on the variable we created in step (2) Sum up: - location stored via PHP - convert keywords either from list OR - auto-detect keywords if possible - convert only X keywords per page - convert keywords in DIV id="content" - convert links and add CORRECT amazon page based on location e.g. [login to view URL], [login to view URL], [login to view URL], [login to view URL], etc Requirements: - FAST - Short script - Comments in code for customization If you know a little about the Amazon API that would be great I will provide a sample Amazon link via PM - we can then use the Amazon search to dynamically create the correct links to the product Looking forward to your bids! Please only bid if you have good experience writing scripts, a little knowledge about Amazon also wouldn't hurt
