Classifieds and Membership

Hello,

There are three things I would like to know how to do.

First, I have 3 membership levels (Start, Build, and Grow). I would like to know how I can configure the classifieds plugin so that the Build members can post for $69/month and the Grow members can post for $49/month?

Second, I would also like to automatically remove/disable the ad after 30 days.

Last, I would like to setup an email that automatically sends to members reminding them that their ad is about to expire.
