I encourage volunteers to meet up with people who don't want to work where the class is right now and pair up as is convenient for them, however a set curriculum by me is the only easy way to make sure no one skipped something because they assumed it fell under another person's jurisdiction. There could also be a lot of unforseen bottlenecks where one person is stuck with everyone ANYWAY while others have nothing to do until that topic is understood by the student. Students also benefit from a consistent learning structure over a longer period of time so that they can "get the hang of it" and then learn in an optimal way given the environment and their own personal style.
tl;dr version: the "semester class by a single teacher" format exists for a reason.
upload it somewhere besides youtube
