Hand out professional business cards that identify you as a matchmaker and offer special deals for matchmaking services.
You have stories to tell, and passions to share, and things to talk about that are more interesting than the weather.
Get noticed for who you are, not what you look like.
This will establish your reputation as a matchmaker and help your name spread through word of mouth if the matches are successful.
In the future you can charge a reasonable fee for making matches and grow from there.
When you're stuck working long hours at the office, other singles are out having a good time.
