But I work in a field that means I'm either a low paid state employee or work for a non-profit. So in the event that my I'm moving, I typically don't have much disposable income as I've sunk most of it into other costs associated with the move.

Typically I'll have family help. Sometimes friends. Or I'll just do it myself - which has worked more than once. But I haven't been in a position to pay for it.
