I live about 3 miles outside of Shepherdstown, and like 7th says, there are few big shops for graphic artists within Shepherdstown, but there are lots of opportunities that are commutable. In town there is Studio 105, which is a small graphics & web design business; check them out at
www.studio105.com Also I would think with that type of work you would have the option to work from home at least part of the week?
If you decide to live in Jefferson County especially the Northern section near Shepherdstown, you don't have to worry about traffic. And housing is affordable again as prices have come down quite alot. For example I have a building lot next to my house that I've dropped about $50k in the past two years.
