Arduino / Nextion TFT sketch

Hi Guys
I have a project that I would like to get a estimate for writing the code
I will be using a Nextion 3.5 as the TFT display and using serial com

So here’s a rough over view and I’m certainly open to any suggestions
I’m building a Tube Pre Amp for my HI FI system
This project is for the audio input selector that will drive Buffered relay circuits and input gain and Clip register.

I will be using a Nextion TFT display, which I have made a template for

Please Note that only one input relay 1 thu 10 on at a time
So when any input is selected it stays active until another gets selected

Analogue Pins
A 1 reads left volume Pot and when its state changes it displays a text message for 300ms with the reading scaled between 1 and 50 Scale

A 2 reads right volume Pot and when its state changes it displays a text message for 300ms with the reading scaled between 1 and 10 Scale

A 3 reads a audio input from the Left side, and at a certain reading (to be determined) Will display text “left input Clip” for 1500ms.

A 4 reads a audio input from the Right side, and at a certain reading (to be determined) Will display text “Right input Clip” for 1500ms.
