In need of advice

[UK_Flipper]

I'm a 19 year old former gymnast, & I want to set up my own gymnastics club.

So far, I've been booked into a gymnastics coaching course to take, and we've bought:
- A floor beam (few feet off the ground)
- A foam module vault
- An air floor (one of these air filled thin strips for tumbling)
- A short air track (tumble track filled with air instead of trampoline tracks)
- A handspring trainer (cylinder with a triangle missing)
- Crash mats
- Spring board

We can't afford a specialist unit at the moment, so we are training here:

That photo was taken before we bought any equipment, so I have no pics yet of the equipment when it's set up.

I'm looking at running 4 classes myself until it gets busy enough to need more coaches. I'm looking to run:
- Preschool gymnastics (2-4 year olds)
- Recreational gymnastics (4-7 year olds)
- Recreational gymnastics 2 (8-11 year olds)
- Teen & Adult open gym (11+)

Is this viable to look at at my age? The finances and insurances will be handled by the martial arts academy we've set up in, all I have to do is advertise and coach.

Any advice for me would be very much appreciated.
