What was the first commercial space vehicle, that is not the property of a government entity; to make a delivery of goods to a community (one or more) in Earth orbit that was at the time occupied by human(s) who arrived by a separate means of transportation.
Looking for the first time, "Bobs Express Space Delivery" was hired to and succeeded in making a delivery. Bob loads the goods into a vehicle he owns and operates, and delivers to someone in space.
I will give 50 bonus points for an answer that includes a copy of the delivery receipt, signed by a member of the space community that received the delivery.
