Consultants also do not get paid vacation, or paid sick leave. They also don't get any of the benefits that a lot of regular employees get. But that's part of the game, they have to account for all of that which is why they earn much more per hour. A lot of those "customer acquisition" tasks cost time and may not necessarily yield a return, but that's part of the extra risk consultants have to assume and why not everyone is willing to do it.
