Industrial Relay Controller with App Interface

I am looking for help writing program and specifying hardware for a relay controller. I have started with m5stack core2 esp32 system but I could not achieve what i wanted and the hardware is too expensive for production.

I would like
- List of hardware needed for my project all CE marked.( I have no idea what works best)
- Software / Fimrware for suggested hardware
- Mobile app Android first IOS later.

Program functionality:
- Control 3 pumps (12v)
- Manual mode for all 3 pumps
- 2 pumps to be activated based on a set time/ day of the week, quantity in ml (Automatic mode).
- Pump 3 runs as a purge function, it must run after pump 1 or 2 to clean the lines.
- Calibration function for pumps 1 and 2.
- Possiblity to connect to wifi network
- Possibility to change timezone
- RTC time for setting pump run times.
- Touch screen to display and set pump run times.
- App to see status / Control pumps / set run times.
- Screen to display time / brand logo / if auto mode is armed.
