I want to buy a book exchange script that will let users register and trade books with other people and charge a fee for completing the transaction. trading will be done locally but it needs to be paypal integrated so people can pay via credit card. would be great if it was based on http://sourceforge.net/projects/php-con/ or http://www.symfony-project.com/ or www.fusebox.org ... if you know of anything, please let me know. if you can custom build it, let me know your price.
