CSS Menu Styling - Drupal

I have a Joomla site using an extension that turns the standard horizontal menu into a drop down menu. The styling needs to be customized to match the site's theme. Here is the development site URL: [[login to view URL]][1] The menu styling on that site needs to match what you see here (hover over the "**Customer Tesimonials**" link to see the drop down style): [[login to view URL]][2] 1. The text bar font on the Dev site should be as **close as possible** to the font on the [[login to view URL]][2] site but does not have to be identical. 2. Navigation bar background does not need to be modified to match the production site. 3. The drop down menu item style on the Dev page should match what is shown on the [[login to view URL]][2] page (hover over the "**Customer Tesimonials**" link to see the style that we need to match for the drop down - yellow background, green text, light green mouse-over color).
