Ahh, I see - well there are a number of template sites out there to choose from, the first that come to mind being Template Monster (templatemonster.com) and Boxed Art (boxedart.com). There are more, but these will give you a general idea of what out there.
Check out the guys at Lucky Marble Templates (luckymarbletemplates.com) - They are great to work with and their templates are not found anywhere else. The templates are VERY easy to change and include fully editable flash and graphics. Prices are generally in the $45 - $70 range and well worth the price. Text Logo customization is free with most purchases.
You will find corporate templates as well as many others.
