Once I learned about technique and the industry, I made a commercial demo, and started to look for work! You will need to choose if you are going to go the Union or Non-Union VO route, and a solid VO class instructor will be able to illustrate the main differences between each.
If non-union (like I did), you can join "pay-to-play" job sites like voices.com, voice1-2-3.com, and the other freelance sites like fiver.com. Spend time on your profiles, and make them look great - these will be your first impression in the marketplace! Also, think about companies that have VO needs. Are there companies near you that produce video or audio routinely? Does their phone system need an upgrade from a robot voice? Do they do corporate training videos?
You can also look into narration! Audible's platform for narrators is called ACX: https://www.acx.com/help/narrators/200484550
Hope that helps!
