Code needed, will pay!, to control 4 rc servo motors with midi/ DAW/ logic/CC#7

Using a Arduino Leonardo, I want to control audio levels on a mixer by physically attaching the Fit Tec FS90R 360 servos to the volume knobs/input channels on the mixer, that is across the room! and control those knobs using Logic Pro X/midi using CC controller message 7(midi vol). I Basically want to "ride" the volume level in real time. Thats it!
attaching the servos is already worked out, I just need an efficient code. If anybody would like to help I will pay!. Thanks,
