All leads have come from my personal network or my reputation as a known entity in a relatively niche field.
Only trouble I've had is invoice approval and waiting for money to be moved, but it has always eventually come through.
Cashflow remains equivalent to when I was an FTE, but I'm working fewer hours per day and working on more interesting things. A lot of that has to do with transitioning out of management, I think. I don't miss it :)
