Failing to be able to buy the sawdust, what would be the best way to

I live in Southeast Kansas, not too far away. In addition to the
suggestions you already have received, I would try sawmills, hardwood
mills and pallet manufacturers. We have a sawmill/pallet manufacturer
in our home town (St. Paul) who has large mounds of sawdust and chips
next to their shop. Another sawmill on the edge of town has some
visible piles.

There are quite a few mills in the SW Missouri area too. I buy
hardwood from a mill near Pierce City. He doesn't cut all of his
stock, but it comes from somewhere.
