It's odd you haven't realized that larger consultancies are just as bad (or worse) -- just bad in different ways. How long have you been dealing with consultants? They're human beings, and 98% of human beings suck. You need to get better at identifying the integrity and value of a human being in current context, and not just pretend that discriminating against whole classes of people in a manner not meaningfully correlated with the qualities you seek is going to somehow make things better for you.
