Why do you need a website?
Websites are excellent tools for expressing yourself (or your company's self) to the world. When someone wants to know about someone or something, they now turn to their computers in search of answers. Just as you are searching for web designers right now, your customers are looking for you. If you're not there, customers can, with a click of a button, find someone doing just what you are doing (with a fancy web site to boot).
Get in the game. Websites are a great way to put your face out there. Whether you're a young business, artist, designer, photographer, or otherwise starving artist, you can gain respect in your industry by having a hot little number on the web to point your prospective clients to.
