How to get help for side projects?

I started Trade Blotter (tradeblotterapp.com) in 2017 after I struggled compiling risk and performance metrics across my many trading accounts. Five years later it’s still not launched.

Like many people working on side projects I’ve worked on it in fits and starts. I really want to launch it and could use some help finishing the backend, some front end and UX work and deploying. It has a Flask backend with a no-framework Bootstrap-based front end. There are some complexities with data acquisition and integrations.

How and where have people asked and received help for their side projects?
