161040 Content Management Site Site

I am looking for a content management website that will deliver turnkey websites and ebooks to subscription customers at 3 different levels, gold silver and bronze for the domain www.ebusinessclub.us. I need a remake of the site to do what it does and more like www.surefirewealth.com. Right now I find the site [login to view URL] too hard to add new products and maintain and think content management would be better. I want a back office that allows me to add and delete products on the fly. This can be a joomla, template also. But it must offer monthly subscription via paypal, and authorise.net. I need the site designed and installed on my server.
