How to get funding for project/website

Hello all, I hope this is the correct medium in which to get advice.

I have a website that I've been developing for over 2 years now. Been in production since Feb 14, 2014 and is ACTIVELY being upgraded, enhanced, etc.

The problem that I'm running into now is that I have so much I want to change/improve with the site, that I'm running out of time to get everything done.

I'd like to figure out how I can try to get funding/donations to do the work so I'm able to take time off from real work, to get more of this project completed. The hard part here, it's a completely free site with no income generated (offsetting ads from hosting costs and I'm still in the negative). 99.9% of people/companies won't give me the time of day because there's no real benefit in investing/donating/etc. Any ideas on how to find locate investors, that may have ideas on HOW to get money back, or people that are passionate about the sport and/or concept.

Hope I'm asking this correctly...
