Have your brother if he doesn't already have one set up an online account with USPS or UPS, FedEx or whoever. Set up the shipping with his name at both ends, copy shipping label to PDF file, send file to you. You copy shipping label, put on package, and answer door with package when they come to pick it up. Your brother sets up everything in his name to and from him. He sets up insurance, and he sets up pick-up date. Your brother is wholy responsible for it.
