We have products that each have their own shipping method. When a customer orders a hardware pack the shipping should go through USPS flat rate. When a customer orders a small amount of our packs (which are separate from the hardware.), the shipping should go through FedEx. When a customer orders a large or wholesale amount of our products the shipping needs to go through Freight Quote. Would need this finished asap. Please feel free to ask any questions. It must be able to be integrated with Woo-Commerce
