I have a curved Cherry that I had a guy with a portable band mill cut up for me. It was a large model mill and he didn't mind playing around some. He cut half way down it, backed up the saw unit, spun the log around, and cut from the other side. The two cuts lined up really close, nothing a planer couldn't remove.
If you have walking trails on your land I would be placing benches all over the place. I have some I made but I don't have ceder so I used red maple. They only last a few years.
