Ethical Hacking - Beginner Course Videos

I'm looking for a starter course of around 5 hours as an introduction to ethical hacking. I may need an intermediate and advanced course after this. Need theory and then show students how to build a test lab at home. You will need to walk them through all steps so you can presume basic IT knowledge but not advanced Linux skills. Ideally, 5 lessons each about one hour but you can break it down into 20 or 30-minute sessions with theory and then hands-on. I'd prefer an English speaker. Please send your past work.
