Fix Paypal on Virtuemart.

Hi There, I have engaged a freelancer to perform modifications on my virtuemart site. Http://id eal ham per.com. He has created functionality to add multiple shipping addresses into a single order. This is done by splitting the order during the customer during checkout into several smaller purchase orders based on the address of each order. E.g., if customer purchase 3 items with 3 locations, there will be 3 purchase order generated. This works fine, as i need to know the items to deliver to multiple addresses. However, there is a problem. Virtuemart only tells paypal how much to pay for ONE of the multiple purchase orders. E.g. If total value is $100, virtuemart will only request $20, the value of only ONE of the purchase orders. You can either fix this, or come up with a new way of generating an order. Maybe one purchase order, but list seperate shipping addresses. I need you to fix this error. Budget $50. Very urgent. Please deliver in 1-2 days.
