OK, here's what we have for now. There are now two paid forums available:
Commercial Marketplace
Classified Listings
For regular posters here who aren't promoting an actual company, CM threads are available for $100/month or less depending on the length of commitment.
Classified Listings are available for $30/month without any links, pics, etc; $60/month with.
Anyone who has a thread in either forum can have an undertitle of "See my Commercial Marketplace thread" or "See my Classified Forum listing", or put the same in their location field if they have an undertitle they don't want to override. Perhaps there might be a way to include "Staking" in there.
The idea here is to provide stakers (or others) looking for a way to stand out from the crowd to be able to promote themselves a little bit. A CM thread allows you a little more freedom in what you can post, and won't get lost in the sea of threads in the staking forums. Same goes for a CL forum listing, but that is just a single post without replies.
