Photos are alway helpful for getting familiar with a project.
That big breaker box you mention with the kill switch on it (disconnect) could easily have a motor contractor in it.

If you are going to post images, get images of the ID plate on the side of your current VFD. Be sure the make and model and any other written data are readable.

There should also be a data plate or maybe two on the motor, get readable images of those.
It wouldn't hurt to open the wire box aka "peckerhead" on the motor and take a photo of that as well.
You should find a small rats nest of wire in there, spread them out a little for the photo. If you see a little sticker on the inside cover of the peckerhead that looks like little lines and numbers, include a photo of that also.
