Well the wiring should be easy but I am not so sure about digging the trench. I ran into that hard pan we have here and it took forever it seemed to gain a foot. I finally got some form nail and drove them into the hard pan and then pried sideways until a chunk of it would break. Should have waited for the rains because it turns to mush then. As for the cement it was always a chore as those bags gain weight with every one that you lift. And it is dead weight too.
