I think you're overthinking it. It's mostly just asking around. Go to a blue collar bar and chat with some of the guys sitting there. In small towns the VFWs or Legions are good choices. Talk to the ones drinking by themselves and that look dirty or sweaty. Hang out at gas stations or a McDonalds. All the people that work these kinds of jobs need to use restrooms and eat. These are two very popular places for them to do those things. Walk through an industrial park and ask the receptionist at each one if they're looking for help. I got several warehouse jobs this way. Call lawn and landscaping services. A lot of these are small single owner operations. Most of these guys are too busy to look for people formally, but they can use the help. I have a buddy who runs a lawn service, he's paying $20/hr no questions asked for help. He's desperate to find people but he's not advertising on the internet because he's not tech savvy. A little empathy goes a long way.
