Crear una página web

Hi! This is what I want to do: I have this CMS [login to view URL] You can see the demo here: [login to view URL] I want to change it and become in a Graphic Subsription Platform and not in a Video Subcription Platform like now. I want something like this [login to view URL] I like the HelloVideo theme and how it like, so I need change the CMS: I would like to use each video page like different graphic pages like this:[login to view URL] I mean when you click in a video, now you go to a video page, if the video is Premium, if you are not Premium Subscriber, you can't see it, and if you are a Premium Subscriber you can see it. I want to see this: When you click in a video page (il wiil be a graphic page) You can see the page and images, but only if you are a premium susbcriber you can see the download buttom, or you can download the file! Is that possible? What is the cost? Remember you don't have to create a CMS, only make a few changes!
