Need Help To Integrate PayPal Adaptive Chained Payments

Hi there, I'm looking for someone to help me to integrate PayPal adaptive payments onto my website which is a multi vendor marketplace. Customer buyer products, payment send to seller as primary receiver and fee/commission is sent to me (site owner) as secondary receiver. I also need help to set it up so that when the seller (primary receiver) issues refund to the customer, fee/commission sent to me (secondary receiver) is automatically deducted and refunded back to the customer.
