Zabbix complete VIDEO COURSE

I would like a multi-class Zabbix and network monitoring tutorial, at first with the most basic concepts (from zero) and increasing the level with each class, starting to beginners and finishing with a professional mastering of the subject, to learn and understand completely how to use Zabbix and become proficient of the subject. The minimum total duration of the course with all classes must at least 8 hours. I need good quality on the recording and the edition of the course. Also, the content has to be original, to be able to use it without restrictions. We will sign a contract of copyrighting cession before ending the project.
