Where do I even begin?

This neglected bonsai was given to my boss and she asked me to see what I could do with it. I have no experience with bonsai and am at a loss on where do even begin trying to shape it up and make it look nice. Any advice is appreciated!

Once again asking for ID help

Greenhouse only had it labeled as "hoya" but not a specific type. I was thinking maybe hoya chelsea because of the rounder leaves?
