Ultimately, you need to make a decent amount of money per hour of work in order to survive, if not prosper. In cases like that I estimate how long the project will take from previous experience with similar jobs and quote a total price based on how much I need per hour That's essentially what a painter, a carpenter, an auto mechanic or even a physician does when telling you how much something is going to cost. Sure, sometimes you get it wrong, especially in the beginning -- but with practice you'll get better at it.
Or you could just say no to jobs like that...
