There are several Campground and RV Park type jobs. Then there are jobs where you can travel with Amusement Theme Parks. We have met a few people who were into Christmas Tree and Fireworks Sales.
Also met a real sweet couple who would property sit and move to different peoples places to be their caretaker. They travel to different properties/homes and care for the yard, home and animals and sometimes small farms or homesteads. They built up a good little business by word of mouth and it works out great for them.
Not sure on the pay or how it works to do any of these as we are retired and choose not to work.
We have met many folks that want to work so they have something to do to stay busy. So the pay isn't a big deal as they aren't doing it for the money. I know if you aren't worried about the money there are lots of volunteer jobs out there too!
