I hugely respect that you were able to bring this idea so far; it's something I've never been able to do. This is work that's 10x better than 95% of side projects or open source work people put on their resumes.

I'm always critical, so take that with a grain of salt.

Your origin story reminded me a lot of Airbnb's. Your motivation is slightly different, but not surprisingly, you're playing in the very, very crowded gig economy app space. Gofundme is pure charity. TaskRabbit is pure transactional odd-jobs. What you're doing is trying to blend the two. I have no idea how to market this.
