This is like google summer of code.
I'd strongly consider participating in this. It's 40x more money than GSoC for a similar time commitment and ~50x more than the money I'd personally make as a full time maintainer (I've been an org admin & mentor for GSoC for the past couple years).
> To participate in the Program, a GSoC Contributor must: be a student or a beginner to open source software development.
