So I am looking forward to see some opinions, thanks a lot for taking your time.

There was an article written recently claiming 92% of blockchain projects fail.

That could be a tough statistic to overcome, even without factoring in other obstacles you face. It may be possible to cut your $10k-$12k estimate by outsourcing development work to those in other countries like india over the internet. I'm not certain if people still do it, or if its still viable from a business perspective, but it used to be fairly common back in the day.
If costs are too high, you may be able to secure help on a volunteer basis if you can describe your project (without giving away essential details) in a way which captures peoples imaginations and excitement. Generating "buzz" and receiving funding could be somewhat correlated.
I think gofundme, kickstarter and more popular, big name, crowdfunding platforms might have a larger userbase. Larger base could translate to higher chance of investors contributing to your project. It might depend on how heavily saturated those platforms are with blockchain related projects and what their failure rate is.
If nothing else you might be able to find people interested in seeing bitcoin and blockchain succeed who might be willing to work on your project for free. I would be interested in working on something like that, if only to learn more, should an opportunity come along.
