The hole diggers that work with your hands. Muscle power. Thats what I use at age 75. Call Lowe's, probably $50/ Or borrrow a pair form someone. Yea put them in the dirt so a 60-70 mph wind does not blow the bldg. away. Call a local building supply co.and just get prices on the lumber and tin. Then add price for nails/screws. Nothing is cheap but it is cheap when you do it!
