Obviously a crane can get to the jobsite. Why not mark the top plate, hire a crane and have them fly the trusses into each spot? Find a buddy to walk the opposite top plate or stand on a set of rolling baker scafolding.

Do you have any setback restrictions or detached building limitations? Where I live, a detached structures can be 20% of the house sqft OR 500sqft (whichever is bigger).
