Request for Directory plugin

Hi!

My Directory contains sport-clubs, schools, etc. which I don't want to charge any money for the listing.
It also has company's in it, and I do want to charge them for their listings.

When somebody adds a free listing I want to review it. If it's indeed free I process the listing, if it is a company I send them feedback to order a subscription. All paid listings can be processed normally.

Hope this can be added to the plugin!

Bye,
