This summer, I want to create a website to sell economic data on a subscription basis. While I'm familiar with WordPress as a blogger (malthusiannectar.wordpress.com), I've never used it for a more complex website. I've looked into using SquareSpace, which has simpler functionality for a novice like myself, but also seems very limited in what it can do. In fact, I can't even set up multiple themes for different pages, which I find extremely frustrating.
My big question: is it possible to set up a subscription / pay site via Word Press? Is there a way to manage user permissions so that I can allow people to view data who pay a fee, but they have no other access rights?
I'm a bit confused as to whether this is possible from my initial readings on the subject.
Also, would purchasing products from a company like Studio Press (for instance) make designing and managing my website simpler?
Any help answering these questions is greatly appreciated. Thank you.
