Sorry I am a bit of a latecomer to this thread. It is actually cheap and easy to get into making fetish movies if you do it right:

All you need is some kind of video cam such as an iPhone, plus a friend to do some kind of fetish activity. You can be in a profitable situation in just a few days. If you don't have an iPhone, you can get a used low end video cam for under $20

If you don't have a friend, go out into the general public and find somebody to kick you in the balls or something. A cardboard sign saying "Kick Me In The Balls - $10" works pretty well. People do this on the Vegas strip all the time:-

For an investment of under $50 you can be making a profit from fetish videos, then improve the quality (and increase the price and volume) later. As it says in the ad, "Just Do It!"
