Shooting hard core scenes for $300? wow.
The biggest market is still the US for Porn and they still want to fuck whats next door...
shooting Hot chicks is what sells wheteher Amateur, Glamour, Niche or Hardcore
Shoot one super hot chick like a "10" in quality and you can sell it a 100 times...the russians are just mass producing and I am sure any Program can tell you what converts and 90% of the time it is Hot girls and American Style Content and being best in Market.
