It you get the far end of the log on the trailer, you're then able to slide a log on with some manipulation, minimal lifting. Cut on the trailer or drag off with power.
If you can start to rustle up people willing to pick up wood, you can just get the wood to a public road, and sell it cheap or give away. More money that way than processing and delivering.
I bought a $1199 Huskee 22t splitter. I can move it myself, easily enough done with 2 people on rough ground. Nothing has stopped it yet. It's not invincible, of course. I rent it to customer's I can trust for $75-100. Let them use it a little bit each day for a week, after their removal job. Doesn't take long to pay for itself, and I've had lots of use. 34t splitters I've rented are way heavier. I roll the machine to the wood.
If you're splitting by hand, you're working too hard.
