Two words Google help!

Hello guys,

My page Scrap metal recycling - Scrap metal recycling prices - Scrap metal buyers was top 5 on google for the past 4 years for the search term "Scrap metal recycling". Then since last Dec-Jan my page completely dropped off.
I checked to see if my site was blacklisted for whatever reason and found out it aint. I have many links hi-mid & lower quality that point to my site. I have a page rank 5 & I have redesigned my site because I tought it would help and still nothing. My site is based at Angelfire.com and thats realy all the information I have for you guys.

Is anyone kind enough to help me or point me in the right direction?
Please look at my site & view source if needed. Any help would be appreciated!

Also is there a certain kind of css, xhtml or so on that is better for google? Any tricks?


Thank you!
