[ Closed ] Paid to post mod

I did a little searching and I didnt find the answer to my question.

Is there a paid to post mod for punbb? For instance, each member has an "account" and you assign a credit value to each action (i.e. new thread=10 credits, reply=5 credits, refer a new member=30 credits, etc). As the user posts in the forum, they rack up credits and you can pay out based on how many credits they have (i.e. 100 credits = $1.00).

Im looking for a mod like this and if one doesn't exist then I would sure be interested in having one made for me. Anyone???
