There's a lesson here on the other side, as well: when you're hiring any kind of contractor (designer, lawyer, etc.) you need to specify not just an hourly rate, but also an estimated number of hours. One person's idea of "getting started" on a project may be an hour or two of work, another's may be several dozen hours. Getting an invoice for many times what you thought you were agreeing to is an unpleasant shock, regardless of how it's resolved.
