Blogger payment system?

Hi,

I was wondering if anyone could help me locate a plugin to assist with blogger payments.

I would like our bloggers to automatically receive funds via Paypal when each of their posts are made public. Basically we will set up a rate system, so the blogger will get a certain amount of money per post, and once a post is published the system sends them the money from our central blog account. This offers an immediate reward for blogging and eliminates the tracking we have to do.

Can anyone point me to such a tool?
