422646 Simple Paypal Split Payment

I need a simple Paypal button script that does this: User clicks to make a Paypal payment for a product I'm selling. I have resellers that are selling my product and I need a paypal button maker script (form) to input their paypal address, my paypal address, the product price, and the redirect url (page customer sees when payment sent) so when a customer buys the product, the payment gets divided... a percentage goes to the reseller and a percentage goes to me (50 / 50) and they get re-directed to the 'payment sent' url outlined in the form. I'm trying to be able to pay my resellers a commission for selling my products. Do you have any other ideas on how to achieve this?
