[ryanb4614]

What they said i get for $2800
-our team will work with you, and work on your site to focus on the 20 most important phrases for your site-and we will add content, clean up the html and make sure everything is organized properly for the engines
-if you like I can send you some info via email so you can see a breakdown of everything we do

I figured I can do this... is there a site that will scan my site and make recommendations or show html erros? Thanks!
