I couldn't find that many paysites to sign up with ....that had content EXACTLY how I wanted it to be. I joined several GOOD sites but they never really had the super closeup shots and the REAL amateur girls. If I did stumble upon a site with real amateur girls, the photos were not LARGE enough and on top of that, were mostly just ripped off from various sources on the internet. You know...the smaller and blurry looking shit. That's when I decided to launch MY OWN website! I wanted to make it JUST how I wanted it to be! That's when I started learning how to schedule the shoots, how to approach the girls to ask them to participate in my shoots, acquiring knowledge regarding html, PHP, web design, marketing ...etc.
I was eventually set up with hosting, processing, my affiliate program ...and the rest was pretty much downhill once I launched the affiliate program. To this day, I have several sales coming through every day ...and all through out the day. It's actually been that way now for over 10 years.
So yeah, it worked out good for me. I know that it does not always work out the same for other content producers, but on the other hand, I am not making MILLIONS of dollars either like some of the HUGE websites do. However, I do make enough to be able to shoot as a FULL TIME JOB ....and my affiliates are happy too!
But sure, that's how I came about working in the adult entertainment industry. It also helps to have contacts that work in the industry too and to stay as active as you can on the webmaster boards.
