Good web design is something that any business can benefit from, regardless of their industry. A website is a priceless advertising tool and a great way to give yourself a `presence` online where your potential clients and customers can learn more about your business and stay up to date with news.
However for a website to be successful, the web design needs to be as good as possible. If the web design is poor, then the website could actually damage your business by making your company look unprofessional, or by getting people to give up on your site right away out of frustration and thus not want to come back. Furthermore if the site is badly designed then you will need to have many re-designs which will cost your company time and money, rather than having it designed just the once which will be far less costly (and less confusing for visitors).
