User posted webinars, events, podcasts, pdfs?

Hi,

I’m an intermediate WordPress developer looking for a solution whereby users can post webinars, podcasts, calendared events, pdf’s, and possibly other media which are paid for when they are posted.

The site I’m developing already includes WooCommerce and the WooCommerce Subscriptions plugin (among many other plugins) so I can use those in some manner to handle payments, but I’m unsure if there’s a plugin out there that can either do what I’m trying to accomplish, can be modified to meet the site’s needs, or can be combined with another plugin in some manner.

It would additionally be helpful to know how I could have such content displayed in a list fashion as well as a calendared fashion. My client would also need the ability to review user submissions before approving their posts.

Does anyone have any advice on how I might tackle such a problem? Any thoughts the community has on this matter would be greatly appreciated.
