Need a meta tag generator/spidering script

[skyraider]

Hey,

I need a script that will "dig" into a user's website when a URL is entered and generate the best keywords to use for meta tags, assuming the website does not already have meta tags. Example:
I enter barrennorth.com. The keywords box comes back with stuff like "adventure", "paddling", "adventure photos" etc. Then, the user is prompted to enter a title and a description to complete meta tag generation.

This script doesn't sound too hard... well, I wouldn't know. Please PM a quote. It needs to be able to run on a Linux server.

Thanks!
