Ask HN: What is my company's next move?

For the past year I've been running a site that can best be described as "IMDB for concerts". I've achieved a good market fit--bands want what I've built--traffic has been increasing, I've got a lot of good things already in place for the next few months. And I've reached the limit of what I (and my one employee) can do on our own. I'm ready to expand.

I've listed some of the strengths; in my mind there is one challenge when it comes to seeking external money: I don't have a clear, short-term path to revenue (aside from traffic-based ads) and I'm worried that this is a problem for potential investors. [note: I believe this is actually a strength for the site because I can focus on growth and the user experience.]

So what is my next move? Apply to something like YC? Seek angel investors? Wait until I'm further along?

Feedback appreciated.
