How can I redirect all orders to my location first for customization?

Does anyone know how to make it so that all the orders come to my location first so I can do some customizing and then I will send them out to the USPS?

Also is there something I’m doing incorrectly because all the orders are saying it will take at least 60 days to arrive. Is there a setting that can be changed to help speed up the arrival time?

Thanks!!
