Anecdote: A good friend made enough money he was able to quit his job as an engineer to provide telecom consulting services directly to small healthcare providers in the North Carolina mountains. Started a small phone company, hired a sales guy, who closes the deal, my friend comes along and walks the company through integrating. He describes it as a hybrid between being a reseller and a managed service provider, but 100% of their revenue is residuals from services his partner sells, and they both live pretty comfortably and happily.
