(joomla)Virtuemart Hack Needed-reward points system

Avg Bid (USD)
Project Budget (USD)
$100 - $300

Project Description:
I need someone qualified in (joomla)virtuemart to write a hack that allows for customer reward points. (you will need to take into consideration that joomla 1.5 is soon to be out and i will be upgrading to that)

example: customer buys product and receives points depending on the amount spent. These points must be stored so that the customer can see how many points they have collected and use them at checkout if the customer wants to.

would also like to see in the shopping cart: how many points they will receive for the order being placed. also there must be a place in the check out process to use these points if the customer wants to.

on the admin side, i will need to be able to confirm these points, also will need to be able to change customers points if needed. will also need to be able to change the points value. i.e $1.00 = 1 point or $2.00 = 1 point.

this hack must work good with community builder and all other joomla components.

ps. my current website offers the point system and if it would be easy enough i would like to merge the current data base (with the customers info and points) into virtuemart.
