But would a "working girl" let you tape the session though? And later sell it for profits, haha....
I think it's not hard to find E Euro girls to make a porno if that's what you want to do. Even American girls, if you have the right people skills. Check out the Girls Gone Wild (no sex) and College Rulez (with sex) vids. There are plenty of young girls who would do some crazy stuffs for (I assume) not a lot of money.
But is that what you want to do? Have you think it through? Personally I'd be quite happy to hire oh say 6 girls of various races for an orgy-filled weekend but there's no way I would let a video with my face in it to get into circulation. Well... for the right price yes... let's say a billion dollars, yes a billion dollars I would be a male performer in a porno. Actually 100 million dollars would do, but not less. Less than 100 mil is not enough for me to buy complete disregard for any consequence.
