You my want to look at PornCMS (
Porn CMS - Simple Adult Website Content Management), which is a plug-and play-paysite content management system. We launch new sites on the network all the time, around 20-50 a month.
The process is easy. Upload your content, tweak the design a little bit, plug in a biller (we do the install for you), and start making money.
It really shouldn't be more difficult than that to launch a paysite in 2018.
