Every project is different and requires a unique amount of work. The price for the work depends on the size of the project.
As of yet, I am not able to present a detailed list because I just started.
I have marked one or two things as “pro-bono” in my portfolio.
Those projects are just old projects where it would be unnecessary to make money of them and some projects are of value to me and the society. It is very unlikely that I take on another pro-bono project.
