Also, the "alt" text for your links are the actual web pages.......for instance, when hovering the mouse over "Home Page" it reads "Home_Page.php" maybe change it to "S&H Home" or something?
To help you with the format, there are a lot of content management systems out there that are open source and free to use:
you might want to add on the pricing page if there is a one-hour minimum charge, otherwise a 15-minute internet setup might prompt the customer to expect to pay 1/4 of the hourly rate.
