New CDL, looking for regional

Like it says, I'm looking for a regional route. My wife is disabled and I can't be out on the road for weeks. The issue I run into is the place I went through to get my CDL isn't a "registered school". They won't tell any other company about their "school curriculum" which was basically 40 hours a week for 3 weeks. Just enough to pass the license exams. I left there because the "trainer" had only been driving "almost a year" (according to him). He spent 90% of the time on his phone either on Facebook marketplace looking for a new pickup truck or talking to friends and family. Every time we stopped at a customer he would pee in the parking lot, even at places that had restrooms available for the drivers (surprisingly, most did and they were clean). My biggest issue was arguing with him every time I went through a construction zone. He claimed "if you don't see a worker, the lowered speed limit isn't in effect". When I spoke to the DM, he said, "we'll get you with another trainer" when he called to set it up he said "it's going to take two drivers HOS to make this run. But after 5 weeks you'll be on your own." The 5 weeks didn't bother me, but I thought it should pay better than $400 a week for 6-7 days a week if they were going to run us like a team. Is this really what trucking is now? I used to go out with my grandfather and it sure seemed like drivers were more professional. I live in northeast Tennessee.
