Hm. Have you thought about going into something related, rather than investing in a masters? There seem to be a lot of Library Sciences people out there who are struggling to find work in the academic field, so they turn to something like law librarianship/copywriting/etc.

I know how you feel - I'm having to learn/relearn a lot of stuff in graphic/web design in order to diversify, as the illo market is pretty bleak at the moment.
