Points System

Hi Everybody

I have somewhat of an unusual request but im hoping somebody can help.

I need to setup a membership website with different levels of subscriptions granting access to different levels of information.

I also need to setup a PPP system that works just with points. I want to allocate certain members with an amount of points 1000 points for example.

Then instead of paying for the post they just exchange some points to read it.

I need their account to be deducted accordingly and i need records to be given to them as to how many points they used on that particular post and what the post information was, like a receipt.

We would also like to keep a copy of the records for reference.

Can anyone help or does anyone have any suggestions.

Kind Regards
