Guitar teacher for guitar school in Oberursel/Taunus

I am looking for a guitar teacher for my guitar school in Oberursel for 2023, initially for one day a week.
The guitar school has existed for 25 years. There are currently one guitar teacher and two guitar teachers teaching. Due to the high demand for lessons, I am still looking for reinforcements.
