I think you guys are talking about rather different things - salaries implies employee, whereas KissMySquirrel, you seem to be talking freelance and per flight hour. It also makes a big difference which country you are in too, of course.
As I mentioned in another recent thread, the norm for UK commercial flying is (in my experience) more based upon time than flying time - day rates and half day rates. This is generally a much better and reasonable bet for the pilot too - otherwise you spend 10 hours working (duty time) for an hours flight time pay.
