A saw mill is the typical way. Look for a sawyer with a portable mill, that can be set up on your property for the day. Otherwise, it depends on what tools you have available. You could split, then clean up with a power plane or hand plane if you have lots of extra time. Dress two edges square on a joiner, then bandsaw the other two edges. If you're splitting with a froe and a helper, then you can get reasonably consistent posts by marking the split, and following the marks. It's not a sawn look, but the froe offers some amount of control.
