Should I ever be hired to build tracks? No, unless you want a track that's fun at the cost of low detail.
You've made me realize that saying "Apply as Builder" in my OP does in fact make it seem like a job interview, haha. My main goal is to find others that have the same interest as myself so that we can do something good for the community. I'll try to make it seem more friendly.
EDIT: Also, I'm only making people apply so I can contact them to tell them when I can give them build trust, and to make sure they aren't really really bad at building or something.
