Found this little sponsor that lets user pay for single porn movies from their sellphone and I just cannot believe how well it converts. My stats are 1:30 or so, it does not pay as well as regular sponsors but converts like a mother fucker.
They pay epass, wire or check I think.

Im not sure it works as well for english sites or other than swedish sites, but the option is there so who knows try it out.
