After browsing around the site, listening and watching the Beginner's Guide to REI Course BP YouTube videos, my first goal is to learn the terminology.

Other videos/forums I have read explain that “you can get one from a lawyer” however that seems to introduce an entirely new process with entirely new questions...”Does that cost anything?”

Books, podcasts, videos, you name it.

The thing to keep in mind is that you will trade more of your time instead, and depending on the scope of the job, amount of times you have successfully completed it, & the situation (if a unit turnover and time is limited) you should factor in a learning curve of watching YouTube videos, trying things for the first time and messing up and having to go to the store to get more materials, etc. 2.

Watch videos, read blogs and forums JUST of your niche.

There's no reason to think they would, but, it looks like a very valuable lot to me that isn't being used well.

Your question without details leaves a lot to the imagination so I'll respond based on assumptions.
