The Norwood, with the chainsaw and your ladder looks interesting. In the early 80's I had a Grandberg chainsaw mill. Cut some 8" x 8" x 10' columns and about 30' of beams. An absolute ton of work. Used them in the house I spent 2 1/2 years building. Wished I had the money for one of the portable bandsaw mills. If you want it to play around with, go for it!! You will need more than just the mill to make money. Some way to move the logs and lumber, other than by hand. Lifting equipment. Heavy truck.
