Think you’ll be ahead to just get your electric provider to put in another 200 A drop.
I can't speak for the OP, but provided I purchased and installed the pole and box, PG&E only wanted $17K for a 100A ag panel install. My pole to be no more than 85' from the pole where they'd hang the transformer.
$17k buys one heck of a lot of gasoline for my 240v inverter...
