There is a compromise. If you are thinking about harvesting and drying lumber then you must have the capacity to surface the rough cut boards. You can buy rough-sawn lumber at a commercial lumber yard that's kiln dried. That would save on surfacing charges to get it to S2S. You could build a simple storage area that's relatively dry and safe from the elements to store it.
If you do buy green lumber and don't mind waiting a year or so before you can use it, for a significant savings, you could use the same storage area as described above as long as it's, also, well ventilated (passively is OK as long as there good air movement). You should stack it properly and it's a good idea to keep it from drying too much too quickly, especially from the ends (applying a product like AnchorSeal would help in this regard), as well as actively removing the moisture from the area for the first few weeks of being cut, (this may already have occurred at the lumber yard, whether properly done or not could be ascertained by asking them and if they shrug their shoulders you can be pretty sure it wasn't. On the other hand, I have bought some quality lumber from lumber yards that didn't follow recommended procedures. Some of them are somewhat anal-retentive in origin anyway.
