There are a variety of excellent hosting services that offer easy-to-use templates enabling anyone who can use document software like Microsoft Word to create a good-looking website. For several years, I have touted weebly.com as an excellent site that was notably easy to use and could get your business online at low cost, even free. I recently used it myself to upgrade the cosmetics of my own site, and to convert my brother-in-law's eCommerce site at awilliamsleather.com.
For completeness, I should also recommend wix.com and gybo.com as good, even free, hosting sites as well. Of course, the traditional hosting big boys like godaddy.com, homestead.com, and smallbusiness.yahoo.com have equivalent tools and have all dropped their pricing for small businesses.
There's just no excuse not to get started.
