Look into the WIA (workforce initiative and opportunity act). It varies from state to state. Mine was through the unemployment agency. Basically it's financial aid for things that aren't college accredited courses, truck driving, welding, etc. It should pay for your schooling in full, it covered all of my $4000 tuition. They actually paid be about $500 in "incentive" checks after I graduated and started working. This way you don't have to do a companies "free school" and then sign on with them for a year. I know you want a straight truck but there's not many class B schools. So just do this, get your class A for free, then drive class B.
My other thought is have your husband find an owner whose willing to let your husband drive solo, with the agreement that you get your permit, and when he's on home time teach you how to drive the truck while you study the rules of having a CDL, then use said truck for your DMV test. Once you have your license operate as a team.
