Congratulations! That's brilliant.
An hour is going to fly by. When I was teaching, I emphasised stretching on your own before class, so we had that time for practice. But I was teaching students who were coming from a taekwondo class, so they knew their stretching routine. With genuine new recruits, that may not be feasible.
I'd be tempted to keep a narrow focus at first. In both my FMA and (brief) fencing experience, much of our time on the front end was devoted to FOOTWORK. A system lives and dies on its footwork in my view. (Substitute "positioning" if you're thinking about grappling and perhaps add "stance" for different systems than mine.) Where to be and how to get there.
I know you're coming, at least partially, from an FMA background. The footwork is genius in those systems. And the presence of a weapon really drives home the importance of controlling angles, distance, timing, etc.
The key is to make learning the footwork fun when someone enters the school envisioning themselves spinning sticks around and so on. My first teachers in eskrima had the training sword they'd swing at us for footwork, things swinging from the ceiling for us to evade, and all sorts. Don't necessarily need all that infrastructure. But perhaps think about interesting ways to train and internalise the footwork.
If I'm remembering correctly, I taught a class where I tucked bandanas in the back of the belts for a bunch of students, and the goal was to snatch your opponent's bandana while keeping yours. So you had to use your footwork to get to your opponent's side and reach the bandana, while also zoning out of your opponent's reach and keeping yours.
I've also done footwork training by getting a padded stick and a boxing glove and (with control of course) gone after students with the stick, able to tap them with the boxing glove lest they forget there's a second weapon in play. Requires a lot of footwork to evade the one without walking straight into the other.
Footwork is crucial. Conveying it in a way that's engaging and helps people onboard the concepts involved, that's where your teaching chops will come in.
Just a thought. Now go enjoy yourself!
