Custom is insanity when you need to be spending your time and money on marketing, not site building. There are so many site owners with sites that are "good enough" making tons more money than site owners focused heavily on perfecting their site. Consumers just don't care that much. They want an easy and fast process for consuming your content. Everything else is window dressing.
Your sales are almost completely dependent on how many visitors you can get into your site per day. Don't waste your time and money on anything else.
That being said,
www.porncms.com starts at $29 a month and includes hosting and the video converter (elevatedX charges an extra $50 a month for video conversion and you have to pay for hosting).
