Token or credit script for wordpress site

I'm running an adult site and need someone to integrate a script where members can purchase points, tokens or credits and use it to tip the models. They will be a total of 7 models that members can choose and tip based on their performance. I'm currently using aMember (for membership) and ccBill (for payment) I will love to integrate both of these system so members can purchase credits or points when they first sign up for a membership. Also needs to be integrated or be able to work with wordpress where I can be able to add the script on each model profile that members can click on it and set the amount of credits or points. Also I will like to show the top members that tip the most and so on. Hope this helps.
