Ciccio, nobody is laughing at you.
But you have unrealistic expectations given the current semiconductor market realities.
You are four people that have spent US$300 over four years on your project.
My definition of this is a hobby.
There are companies with dozens to hundreds of people that can't ship existing product because they can't get parts.
Not just FPGAs, but microcontrollers, memory, discrete devices. All types are under severe allocation by vendors.
So you really do need to open your eyes and look at the real world.
