Oscommerce - referral feature

I need a feature that will enable customer check out in the following manner. Instead of inserting a payment I need these items to occur: 1) an email needs be forwarded to the manufacturer/s (if products selected are from different manufacturers) with the order and customer information. An copy of the email needs to sent to the store administrator. 2) a referral fee (unique to each manufacturer) will be deducted from the manufacturer's account. the referral fee will be a percentage of the order. the module needs to have the capability to verify that the amount in the manufacturer's account is equal to or greater then the sum being deducted. 3) an email needs to be generated when the account goes down to a certain amount.
