The common problem with hackathons is that you usually don't get to vet your team members/co-founders very well. Building a is a marathon not a sprint, so it's best to make sure your co-founders are really people you want to spend a TON of time with.

Also, transacting $5000 is good, but you probably shouldn't quit your job until you can prove that its replicable and profitable (or at least sustainable).

To be perfectly honest, your phrasing made it sound like you had generated $5k in revenue, in which case quitting would probably be a good idea. $5000 in contingent donations is a whole different animal. If I were you, I would keep working on it during nights and weekends in order to test whether it will continue to gain traction.
