Seeking to have 2 payment systems.

[gio14]

I currently have a point system wrking on my site thru alpha user points, users accumulate "Points"  and they can uses these to spend in virtuemart thru Nordgraphs plugin.  All good.  But now i have 2 classes of products A and and products B

I would like to use the point system points to be spent to purchase products A and now i need some sort of currency on my site "My Bucks" which would be something like 100 "" equal 1$.  So i need some way for the user to convert real money into "my bucks".  How can i do this seems like i basically needs some converter for the user and some way to store their "my bucks" in their profile.

Please steer me in the right direction, I'm a bit stuck on how to make this work.
Thnx
