PHPizabi Music Store

We are creating a social networking website running off of PHPizabi.? We need to create a music listing for the site.? The listing is for any musician or filmmaker to sell his own music or films on his personal page.? The payment gateway we will use is Paypal and we will not charge the users any fees to sell their stuff. They will be allowed to list items that will show up on their personal page.? We will offer them a list of categories that they can list it under. We will need to also create a search box for people to search for music for sale.
