Looking to pick the brain of some that has run a successful directory site

[stymie]

Hey all! Long story short, I am helping my wife with a project that is going to be a directory for a specific segment of the wedding industry. I am fairly skilled at SEO, but thought I would reach out here to see if any past or current directory owners have any tips for filling it up as soon as possible. What worked best for you? Facebook ads? Niche-specific forums? Something else?

Just trying to avoid wasting our time on methods that may take months to see results if there are others that may bear fruit in weeks or days.
