This market is already (at least partially) covered by small consulting shops which provide sales front for competent freelancers who don't feel like doing the whole corporate networking&sales ritual.
Well, the companies I know tend to do their recruiting based on word-of-mouth recomendations - so they have to know you from some previous job or you need to be recommended by someone etc. It's a tiny sample of a couple companies though, and that probably doesn't generalize to all "small consulting shops".
