Setting up rows for new blueberries

Just got back from Buckatunna, Mississippi with nearly 2400 blueberry plants. 1150 Tifblue, 600 Britewell, and 600 Premier. Loaded them one on top of the other in our cattle trailer. There were so many the trailer was almost as heavy as when it's full of cattle. Tomorrow we are going to lay out the new rows. 12 feet between rows and 5 feet between plants. We should have 35 rows if all goes according to plan. We bought a used surveying transit just for this purpose. Hopefully the transit will keep us straight.
