I really want this to happen, how can I help?
Thanks for asking (or, better put, thanks to myself to create this question to tell you how to help!).
If you want to help reach the funding goal, the best thing you can do is sharing this site with your network: FB, LinkedIn, Twitter, internal university mailing list, etc.
Also, sharing would be very much appreciated if you already got a job via the take-home challenge site and you want to show your gratitude!
