I believe the most important part of any web solution is the customer experience. If text is too long, it will go unread. If it stretches too far across the page, the reader will lose their place and give up. If the information they’re looking for isn’t easy to find, they’ll go elsewhere. If the page takes too long to download, they’ll click on the next link in their search result.
The particular nature of a business does not matter to a good designer. Our job is to interpret your needs and your customer and design to attract more business to yours.
