Ask HN: How to find a good creative partner for solo projects?

Some of us on HN have ideas we want to turn into products, but lack the creative talent to put a pretty face on an otherwise solid idea.

I know crowdsourcing may fit some quick/simple projects, but for more complex projects that require ongoing collaboration and effort, it seems a more dedicated partner would be a better fit.

What are some good ways to find solid creative talent to help partner for solo projects?
