I need an Arduino engineer for a Sound activated dispenser project

I need help building my Arduino code for a project. I am trying to build a sound activated snack dispenser. My plan is to use a sound sensor module to detect a noise like hands clapping or a dog barking to activate the micro servo SG90 to rotate starting from 0 degrees then go to 180 degrees for 4 seconds then return to 0 degrees until the sound sensor detects a noise again. Once the micro servo SG90 motor rotates from 0 to 180 then back to 0 degrees, the LCD display with a shift register (SN74HC595N) will display the message "Snacks ready" and a passive buzzer will beep for 2 second after the snack has been dispensed. Then a IR receiver module and remote will be used to turn on or off the whole system so that if the system is off and the sound sensor detects a noise, the micro servo SG90 motor will not rotate and the LCD and passive buzzer will not work. I need this done by the latest on Wednesday, October 13th, 2021 at 12:00 PM Eastern time. Attached is the code I was working on so far but had trouble with. Attached is a video of the prototype with the devices and cables connected to the breadboard and Arduino Mega board. I am willing to pay extra if need be due to the time constraint.
