How to integrate virtuemart with Liberty Reserver

[zaheer45]

Hello,
i want to setup integration (i think integration) of virtuemart with liiberty reserver, how to do this?
i want to when a user logged in my site, his LR account balance should be shown at the top left of somewhere on the site, registered user should be able to add fund in liberty account and they should be able to pay the price for the products purchase from my site via LR.
when a user click on checkout it should go to LR site and after payment completes it should returned back to my site.
Any suggestion? idea? Solution?
