Ask HN: How to find a business partner?

The last few months I've been working on a company by myself. I have a solid prototype and path to monetization, but I'm running out of energy. I need to find a partner who's willing to work for part of the company before I completely burn out.

Specifically I need to find a mobile engineer who's willing to build an android app. I just have no idea where to start looking. Any advice or would be appreciated.
