Sorry to drag:
If you have enough and thought about it, when do you going to start it? Yes, it is most profitable business I agree it and we can find stars in cheap price but needs good studio and devices. But money is not all and there are many more business you can come with but you always come with negative and some one thinking of generating idea and just trying to read your your psychology and inclination of your brain.  Dude be positive and show your positive side.  There are thousands of business that can be boomed along with porn, let the local people do it with a camera like the dj tantrik.

Dude Show your positive side.
