URL format

[ayok]

I have a problem with one of my client about the url. I've tried to implement clean URL for the site. The old URL was like index.php?id=12&item=22&page=about_us. So far I've changed it to site.com/12-22-about_us.html.

 

However, it still looks messy with all the number and he's still unhappy with it. How can I get rid of those numbers without messing with the query?

 

Thank you,
