Need advice for a web solution. [APPRECIATED]

Hello,
I am in need of a service in which I can host my main sales page with different subscription packages and once they subscribe they have access to a members area which has listings of different items that they click on and can read.

What kind of wordpress plugins/themes would I need for this.

Any help would be greatly appreciated.

I've just done a quick search and found this article with a list of the best membership plugins - http://www.wpbeginner.com/plugins/5-best-wordpress-membership-plugins-compared/
