This could work, it can't hurt to try. Find a good golf course close to where your business is based. Find out the name of the superintendent, call and ask if there is a time this week he or she would have a few minutes to speak to you in person about finding help. They have extremely high standards, know the market, and may be able to help you with an idea or name of a couple good people they were unable to hire.
Good luck with your search.
