Market yourself on social media if you are serious about making some income. Chances are it won’t happen overnight, but you’ll get the ball rolling at least. Make some business cards to hand out to people and places that you go, they do come in handy.
Also, get in the habit of researching notary-related topics online with google searches and of course, notary websites such as Notary Cafe. I find the information on this website and others valuable. Good luck!
