User can submit and import facebook events from own fb pages..

Hi guys,
Can u guys help out with the following feature user can submit and import facebook events from their own fb pages user can do the same with facebook groups visitors can join group and events from wp

This feature should work with a payment gateway,...i should be able to monetize this, frontend submission, and by user i mean a regular subscriber that upon subscription becomes a event publisher

I will be running this in a multisite,...but this particular feature needs a front end submission capability
