The Community of Disc Golfers and About All Things Disc Golf
North from were eagle road turns to a strait line off road to the East tree line towards second back yard South back to the road.
Looks like quite a bit of property. The squares are those acres?
If I wasn't working on a course in SW MI, I'd give a crack at it. Just stick with a local experienced designer. Any course designer will want to survey the land before trying to make up a map or any supporting material.
Good luck and keep growing Michigan disc golf.
