Most people that we create websites for are either owners of a business or employees of a business.  Either way, all these businesses with new websites are most likely looking to attract new customers.  One of the best ways to show potential customers what your company can do for them is to have a portfolio of previous work on your website.  A portfolio could be categorized into different categories based on different types of work that you perform or different services you provide.  Before-and-after pictures are a great way to make your actions speak louder than words.  Make it fun and colorful and potential customers could spend quite a lot of time on your website!
