Moving Large Oil Paintings

Hi pros! I work at a historic house museum with no curator/collections manager, (and therefore no one to ask) and we just received a call to go and pick up two large oil paintings on canvas 36x30. Does anyone have advice on the best way to transport these items? I can order any boxes needed etc. The distance is only 2 miles. Yes, I know we should only take in items if we have all the knowledge required to collect and care for them, but there are lots of limitations to a historic house and not accepting these items is not an option. I am just an assistant trying to do what is best for these paintings.
