Other Limit replies in a topic of a certain forum to 1?

Looking at the forum permissions so that I can have users able to create a topic in a forum but they cannot reply to their own topic and other users can only post 1 reply.
Nothing is jumping out at me, is this even possible to do?

You will need a custom to do that.

You will need a custom to do that.

What kind of a cost and time frame are we looking at?
