Brian Chesky, of AirBnB, gave a talk at startup school that touched on this topic: http://www.justin.tv/startupschool/b/272180383

His advice was that "you always focus on supply first... then you shift to demand." Here that would mean to try to grab producers before promoters.

The idea is that producers are more willing to list their movies on your site, no harm done, but promoters won't be interested unless you have some movies for them to choose from.

From Startup School as well, Adam D'Angelo said they answered a lot of questions themselves at first, Mark Zuckerberg said they had interns scrape the course info manually, Brian Chesky talked about how they recruited the first people themselves by door-to-door basically.

Summed up by D'Angelo: "it doesn't matter if it doesn't scale if it strengthens your position". Though I don't know how that applies to your case, if there's anything you can do to get things started.

2cts I think he said go to the harder side 1st (if it's supply, supply, if it's demand, demand) and then shift to the easier side. For me was the best talk from Startup School 2010 with its story: "Go to your users"!

So far I've found this to be true with PPM.

It's hard to get producers to sign up without promoters being on board, but not nearly as hard as the opposite situation.
