develop synthesizer drawing

I'm looking for someone who can develop me a synthesizer drawing that I want to build.
The synthesizer will be made up of several parts. I want to start with the first part and if the price suits me we will move on to the next part
The requirements according to the picture I sent you
4 VCO - Voltage Controlled Oscillator
LED lamp for every sound wave
Frequency Potentiometer change for each VCO
And sound (PL PLUG) came out for each sound wave
A top screen that shows the sound waves and changes that occur with the change of frequency
