You have a business. You have a budget. Why would you bother making a website? Your advertising dollars are already tied up in so many other things. If you look at all the different forms of advertising websites have one of the best returns on their investment.
In reality, if you look at any business website, it is a form of advertising. Websites are designed to simulate flyers, bulletin boards, brochures and everything in between. The main difference is that when your flyer is thrown out the website is still working. When you ad time has run out your website continues to produce.The other benefit, websites are sooo cheap compared to everything else!
