girls wont share the profits, i guess, but are to be seen as a one-time investment for the producers. with each production these producers take a certain risk, as they invest before a return in the market, but if the series or the flick can be sold several times to different customers, that risk will pay off very well. additionally there will be done several series and flicks in one single session with high probability. these series are brought to the marked step by step, so that if a girl becomes requested by the users, the demand can be satisfied, even if the performer isn't in the porn business anymore.
these performers get paid according to industry standards then - i suppose
