Try to use an external style sheet..easier to manage and you could hide the table or create some CSS boxes..Apart from that not a bad site..
If you must use the Contact Us an a Mailto, try to add something like..
?Subject=Email From Website
after the mail to, this will fill in the Subject part of the email automatically. A better way would be to put a simple form onto a page, looks smarter and more professional.
The top/header and links seen to jump around a little from page to page.
Same as the previous post for the Font..Try to stick to a font that everyone has got..I'll do an example for you..
