Up until recently you might get funding as a teacher (of something considered worth teaching, I doubt 'leaving Windows for Linux' would be considered such) but even that is subject to radical change with AI getting its grubby digital fingers everywhere in education.

Maybe start doing it out of passion (you mentioned love, I imagine it was more about people switching to Linux than getting paid to help them do it?) and if enough people find you're doing a terrific job you might get some support, eve from some local authority willing to promote such a change?
