To sell ppc management services

I’ve been managing ppc campaigns for a couple years now, and the other day I was thinking about starting a ppc management or consulting service. I just wanted to get some feedback from those of you who have done so in the past to see how it has been for you. I would think that most consumers are still a bit sceptical as to the profitability of doing ppc advertising, but I also think that many of them don’t fully understand it, or have had a negative experience in the past. So, I figure part of the problem would be getting them to accept that ppc can actually work, if done right.
Any thoughts would be much appreciated.
