actually i am sure you will have to digg in a bit more than one day to make all work as you might expect it!
Okay, anyway, you would need to check the following:
* Landing Page
a certain reduced langing page template is not included in CC. you would need to create a page template for it -> PHP, HTML (there are easy tutorials, but anyway, it's code)
* Membership functionality
You can add a lot of cool stuff with WooCommerce. it's for free, and many great premium extensions available also. If you plan to have BuddyPress installed, it does not communicate with WooCommerce user data, so you would need to get an extension here, too.
* Email Marketing
Several cool plugins out there to integrate the common email newsletter systems.
Maybe more to come, and strongly depending on what you expect. If you don't want to step into code, try to find the plugins and solutions that work out of the box as you like.
hope this helps and gives some hints to the right direction.
