Now assuming I don't quality to be a Authorized Shipping Outlet with UPS, however, I do qualify to be an Authorized Ship Center with FedEx, I would then be able to accept packages and ship only via FedEx. This doesn't conflict with just parcel or package receiving from any couriers (ie. DHL, FedEx, UPS, USPS) correct?
Correct. Feel free to PM me with additional questions. Again I would have serious reservations about the business model you are looking at, but I can at least answer questions from a UPS perspective.
