This article got me more emotionally invested in it than most feature films to be honest. The amazon reviews for Berggoetz's book are also pretty funny, I have a sneaking suspicion he wrote half of them.
Not sure exactly what sort of work you want information on but I read the book "Film and Video Budgets 6" a few months ago and there is a lot of good info in it.
One section goes in detail about every job on set, what their duties are, and how much they typically get paid (in the US) on low to high budgets.
It also has a bunch of budget templates and stuff you can download, they are all Excell spreadsheets.
It's all informative and easy to read. here's the link to it on amazon
Edit: It also goes in depth on every line item on the sample budgets and stuff, and there are other sections
50 Greatest Bond Cars book. My wife got it for me this year for Christmas and it’s very cool.

Besides making docs for 20 years, I've taught high school sophmores in NJ for the last 3 years. Asking them what they want to make a film about is pretty much useless as half the responses will be a variation on "how teens today have it rougher than previous generations". After MUCH trial and error, the day-to-day media teacher and myself have come up with a good plan, divide the class into groups of 4-5 (more than that, things get unyieldy, less than that, work won't get done as kids won't be able to always make shoots or be there on important days because of testing or whatever). Ask for them to present 3 pitches on a subject that can't be ABOUT THEMSELVES OR TEENS TODAY. Pick the best one, which means, the one that they actually have a chance of finishing, not the one that is necessarily the 'best' film idea. Then work with them over the course of xxx weeks to get it done. It helps if you have an idea of what it takes to make a doc. I'd recommend this book, https://www.amazon.com/Get-Close-Lean-Documentary-Filmmaking/dp/0190909900 great overview of making a doc with a small team and discusses all the practical aspects including cameras, sound and editing.
