If you are more agriculturally minded, there is still a great demand for sheep shearers, believe it or not- depending on where you live, you can make very decent money. There is a shortage of shearers in MI and many other places. You have to be willing to travel, but that could provide great opportunities for jobs all over the country and possibly the world if you are interested.
As a shearer myself- it takes a lot of endurance and practice to become good at it. But as long as there are wool sheep in the world, they will need their fleeces removed. And it's the type of job where there are few do-it-yourselfers.
There are shearing schools scattered around the country, or do what many shearers did and go to Australia, New Zealand, or even Ireland to learn. Or apprentice with an experienced shearer.
I also hear that there's a shortage of good farriers in many areas, also saddlemakers.
There are also professional cattle hoof trimmers out there making good money.
You could look into becoming an artifical insemination technician. That's all the dairies use nowadays. Obviously you have to be in a dairy region like MI or CA to be productive, but it's a great job, needed year-round, and the training is not very expensive. Some AI techs become embryo transfer techs for veterinarians, or even embryologists (these typically have a bachelors degree though).
Just a few ideas that weren't mentioned.
