Make a Tinder profile and put your contact info in there. Even though the people there aren't currently in a relationship, a decent amount could probably make use of relationship advice.

Do the first consultation free to learn about what their problems are (you could post a pro-bono Clarity link on your Tinder profile), and give them some basic pointers on that first call to try out. If they work they'll tell their friends about you, and they'll call you back for follow up advice after their first date, and you might even get press if someone in the press notices, since it would be kind of a fun story.
