What are some types of coaches/teachers I can hire to improve my work life ? (Interview skills, resume building, emotional intelligence)

For example in a book I’ve been reading the author mentioned improv classes which improves your sales skills as you can act quickly and be ready for objections. He also mentioned a voice coach to improve the confidence and cadence in your voice.

I don’t think I’m confident enough yet to try the improv classes just yet , and voice coaches are a little more difficult to find.
