CSS drop down menu - replace existing

"Burra" This is the website that requires work: [login to view URL] "CFS" This is the reference site: [login to view URL] Modify the Burra site so the drop down menu is of the same style as the dark grey navBar in CFS. The motivation for this is that especially on some of the submenus the dropdown disappears if the user accidently rolls off on the Burra site. This job is to develop the CSS/HTML as above, and apply to every page in the Burra site. Please note the code for this site is untidy, it was developed in iWeb then had the dropdown added later FTP to the Burra site will be given to successful bidder. In your bid please include some example of your drop down menus you have done.
