Ask around. I would bet that there is a neighbour not far away that has a portable mill you could hire for a day or two once you have a pile of logs. Probably a small sawmill with cheap woodchips not terribly far away either.
Look around for rock piles in the woods. There are so many overgrown old homesteads where they were piling up rocks for pasture. That's a lot of labour already done for you if you want to incorporate natiral stone that is.
Find some clay. Dig some holes, check ditches along roads, talk to local contractors...
The bark peals off the logs really easy in the spring to mid summer. After that it becomes more laborious.
Axe, machete, string, hammer, draw knife, chisels, plumb bob, hose with water? (For a level), shovel, wheel barrow.... The list goes on but you can do it with the basics.
