Pole barns rank as one of the easiest buildings to put up, especially if you buy ready made trusses you can't go wrong. The hard part is digging the holes. I think my arms are still sore from when I dug the holes for my chicken coop. The trick is to get the post holes at least 4' deep and don't use any concrete in them. They rot faster if cemented, and any less than 48" you risk them lifting up.
My pole barn post holes were dug with an skid loader mounted hydraulic motor power auger. Maybe 14-16 inches in diameter. Drilled well below the freeze line. After the holes were drilled they needed to be inspected by the local building inspectors for correct depth. After inspection dry bagged concrete mix was dumped in to serve as the base the pressure treated post would rest on. Fill dirt was used around the posts. The concrete sets by absorbing moisture from the ground. No water was used.
What amazed me was that two Amish men put up the entire building in two days. The only ladder they had was a 6 foot step ladder. They used the stringers as steps to climb to the top of the building. Trusses were set in place pointing down, swung like a pendulum, and flipped up. They did use air power nailers and screw guns. Construction was a site to see. It would have taken me all summer!
Another three man crew poured the concrete floor. They had engine power buggies for moving the concrete. Used a laser rotary level to set a reference level. Then a stick was set on the top of the wet concrete. It had a sound alarm to detect the laser. One sound for to low another for too high. The concrete screet was interesting. A vibrating 10 ft. metal board, powered by something that looked by a weed wacker engine. It all made the job look easy. I know that wasn't the case judging by the sweat pouring off their faces.
