I know UI designers (who work on iPhone & iPad apps) that make $120-150 per hour for their work and they work for themselves, no agency. Of course your goal is to have 40 hours a week of billable work but it never really works out like that :)

40 hours a week of billable work is damn near impossible. Even if I could find that much work, I wouldn't be able to handle it on a regular basis.
