Nobody has mentioned Harris Cyclery as a model. Harris is the closest thing I know of on the web which caters specifically to commuter/transportational/touring cycling.
The big problem is that commuters and touring guys don't buy a lot of stuff compared to the roadies or the mountainbikers who have to have the latest and greatest. It's a hard market already, and by limiting your sales to those who buy the most, you are just putting more of a load on your shoulders.
