Free and open cooperation projects always carry the risk of financing.
That is, they go forward hand in hand with volunteers and end up dying. I'm not saying it's fair. Absolutely not. But it is reality.
I have been working and collaborating for years with free and open source software projects: Linux, Gnu, various distributions.
The only way to carry them out is by vocation with selfless effort,
For example, only Ubuntu, from the hand of a billionaire, has managed to detach itself and assume a commercial profile on the one hand and free on the other.
I wish you the best of luck. But it is very difficult.
