Fame
You could be like Patti Stanger and get your own reality TV show on Bravo, as well as a jewelry line, several popular dating advice blogs, and publish several books on dating. Successful matchmakers tend to work with rich people, who are often famous. That fame may just rub off on you.
It will all depend upon your skill level. Being semi-alright at matching people up may earn you a living, but it's not going to bring in the big bucks and fame that comes along with finding Leonardo DiCaprio a wife.
