Trade school for preppers?

My bestie found out that we would both be eligible for a grant to take a technical school program. Since I'm prepping with the idea of eventually having a small homestead and being semi-retired in 20 years, I really want to take advantage of some classes.

Especially if it's going to be hard finding men who will provide repair services and the like without ripping me off as a single woman. Mostly interested in carpentry and I've always wanted to learn to build custom furniture but that would also let me build and frame simple buildings like small barns or sheds by myself. They have a electricians course too, might be good if I ever want to do solar panels or alternative energy.

I'm also looking for some classes geared towards small scale agriculture and livestock care. Although I don't think I could slaughter my own stock, I'd like to ethically grow them and be able to process them for food once they had been slaughtered as humanely as possible.

Really, I'm just trying to think of useful skills to add to my resume if I ever need to build or repair my own shelter. As well as skills that would make it worth bartering with me since I don't have a lot of valuable stuff.
