Ask HN: Best way to fund a small video game

Basically I'm working on a small Unity game with a contractor, so far I've put in about 2k for art and assets, the contractor will probably end up being another 2k or so.

I plan on spending up to 10k of my own money. At which point should I seek out funding, can I hire someone to run social media and build hype ?

Or should I self publish my small game with what limited resources I have ?
