It would take as long as it takes you to get to your nearest US Post Office. There they can tell you how long it would take to deliver it.
It takes 3 x 6 = 18 man hours to dig 12 holes. Therefore it takes 18/12 = 1.5 man hours to dig 1 hole. To dig 9 holes takes 9 x 1.5 man hours = 13.5 man hours If 2 men are working then they take 13.5/2 = 6.75 hours or 6 hours 45 minutes.
IT takes 10 years
