Setting up a trial period for users

Hello all,

I have a question regarding the Membership plugin. I am trying to create a website with three tiers of users:

-Free 14 Day Trial

-Paid Subscription 1

-Paid Subscription 2

What these users would be doing is paying to create a WordPress site. So, my question is:

1) How would I create a Free 14 Day Trial membership, and then after 14 days restrict their access to the WordPress sites they have created?

I appreciate any and all help with this!
