Godot doesn't seem to be a good option for Freelancing currently.
The solution is to use what you like for your pleasure and principle.
And at the same time become good at a popular tool like Unity.
For your own projects you'd be using Godot and for others or work, you'd be using Unity.
That seems to be the only solution.
I was looking on Fiverr and found very few gigs with no reviews.
One can also try praying that Godot becomes the most popular engine, but Science has shown us that it doesn't work.
