How much does an actress makes in an indy flim?

There is no answer. The actors/actresses will get at least scale (union minimum), usually more, although there is no upper limit. If the film is independent (and non-union), the actors may not even be paid. In addition to, or instead of pay, they may get points (percentage of the profits) -- which could be a lot, or nothing. It isn't a dumb question. There just isn't an answer for it.
