Epic is not WebPower or Pro Adult I'd guess
but, they have a fair number of sites.
There are those that have started with less I suspect. If you want it bad enough or can come up with content on the cheap you can do it..
Some start with a Nasty lets say and then break out on their own. Or you struggle for a while and hookup with a bigger fish.
If you don't have the bucks, do free sites or AVS. TGP even.
