Tasmota - create a script in Tasmota for an electric device

I am looking for a freelancer who can create a script in Tasmota for my Smart plug for my device at home. The script should allow the user to turn the device on and off on a specific condition (I'll write on chat). I do not require any integration with a specific platform or app.

Also, I need explanation step by step what to do.
The freelancer will help me step by step to achieve the final result. For example by Freelancer chat, skype, zoom, screen sharing, etc.

Ideal Skills and Experience:
- Knowledge of Tasmota and scripting
