Do a 'right' click of the mouse on the page and then click 'view source'
Scroll down and you will see this for Mexico:
<a href="site.jsp?SiteId=509">Baja California Sur</a>
<a href="site.jsp?SiteId=552">Todo Mexico</a>
so I cannot be of assistance any further at this time.
You might want to go to the 'job' forum to hire a programmer to complete your needs.
