You cannot do everything by yourself.
So far, I've managed most of it.
I noticed there's plenty of people looking to improve the tool you have built. Have you thought on making it open source? Allow people to contribute and guarantee it will be maintained in the long term? What would be the pros and cons?
It's basically just a bunch of shell scripts. There's not much to make open source, and my spaghetti code wasn't really meant to be open source.
