Hi! We plan to do it ourselves, primarily by hand. There are 4 of us here on the property.
We have quite a lot of wood to work with, as you can see in the photo of the hillside in the link. We would like to use as much of that as possible.
In the link below there is a panorama view of hillside, complete with good dog going after ground squirrels. As you can see it has become the de facto wood storage area.
There is also an overhead view with the hillside outlined in blue

That perc test looks easy enough to do; I'll get that started today.
