Pay WP Users for writing on my blog

Hi,

I want to pay the users that write on my WP blog. I was wondering if you know of a plugin that could count the unique views a post has got, and eventually compute how much money I owe a user. For example, if I want to pay $1 for 1000 unique visitors, for a post that has got 2400 unique views I want the plugin to show the user I owe him/her $2.4. All plugins I’ve found are not that complex…

Thanks for your time!
