I agree that promising any bug fix for free is silly and not necessary. If you want to demonstrate good will, you can at your own discretion not charge them for your moronic bugs, the ones where you go "oh fuck this is embarrassing" when you figure it out. So their expectation will be set at paying for your work hourly, but once in a while you will waive the fee. I think people will appreciate it more.
