Hi, I want to make a firework detonator using a dollar store timer, so I need to amplify 20mV to 6-9V to ignite an 'estes model rocket igniter'. How could I do this? I know next to nothing about electonics

How have you measured your 20mV from the buzzer ? 20mV through a buzzer will be pretty much inaudable.
You also need a circuit that ignores any beeps that come from pressing the buzzer buttons or you'll fry yourself.
