CSF Fishing

I have been looking for a used boat for months in the Midwest. I have been on craigslist, FB marketplace, ebay, dealer websites and everything else I can think of on nearly a daily basis. I cannot seem to find a boat within my price range that does not get sold in a day or is less than 500+ miles away. Does anyone know of any other ways of finding for sale by owner boats for sale? What I am looking for, should be the standard bass boat that is for sale but has been a huge process to get one located. (Fiberglass, 150 HP, 18-20 ft, 2000 and newer and under 20K). I need to get one purchased asap. Any info would be much appreciated.
