Howdy,
Just buy an air nailer and compresser and be done with it. Go to harborfreight.com and find a store in your area. Air nailers are dirt cheap $20 USD and a compresser runs around $50 USD. Chuck in some nails and taxes $100 USD. Crack your wallot and save your arm. :-D
Why dig a hole with you hands when you can use a shovel.
