Bruce,

I don't think your story is unique. The vast majority of business in the USA is small business and the vast majority of small business has fewer than five employees. Joe who fixes the trucks is interested in computers but he's never heard of msconfig and expects you to walk him through it. If you're not charging, an upgrade that requires this for every customer could knock you out of business. Even if you do charge, a support call that would be regarded as a trifle by a Corporate may be a big problem for a small business customer who considers that you chose the technology so if it keeps breaking, that's your problem. "Heck, if the awnings we supply kept breaking every 5 minutes, I gotta fix 'em for free, and so do you." So it's a completely different prospect- and one that will receive increasing attention now that the corporate market is saturated by IT services, and providers are switching target to small business.
