Payment questions

Hello, sorry for late response, I wasnt around for a week. I figured out my last issue about image upload was caused by another plugin i had installed, so that problem has been solved now.

Please i have a question,
on my website, am allowing customers to upload their items from front-end to sell, assuming someone wants to buy this product uploaded by a customer, once payment is made, whose paypal account does payment go into, mine the site owner’s paypal, or the customer(owner of the product)’s paypal account.

How do i set it for payment to be made to customers (owner of product)’s paypal account, and a certain percentage to automatically go into my paypal account immediately payment is made to the customer (owner of the products) paypal account?

many thanks
