Try smaller paving,concrete and construction companies . Maybe you have to drive a mixer or tri axle first. Or the lowly water truck. Doesn't look like the greatest year for dump work. Just keep trying. Good luck.
You could always try a local landscaping company or like Cat said asphalt or paving companies, the only downside is alot of those companies have layoffs in the winter time, if you cant get any of them to give you a try you could always get some experience in a garbage truck first and then try to switch over.
