Ask HN: Where can I find good Game UI Designers

I'm looking to hire a designer for art direction of a game I'm writing. I've been searching HN for ideas on how to recruit designers; and I've tried the following

- Finding work I like on Dribbble and contacting the designers

- Finding designers through HN Search

- Elance

Unfortunately either the quality of the portfolios is the bog standard SaaS type stuff I can find on ThemeForest or the designers in question are always too busy / don't bother replying to my introductory email.

I have a well written brief (GDD ~ 50 pages), a decent budget and being a full stack developer, I'd like to think that I'm a fun and understanding guy to work with.

Has anyone got any recommendations of amazing UX people they can give me, or tips on where I might be going wrong?
