Do you like languages, OP?
I have a useless degree and masters from 15 years ago. Can't do teaching because I don't have minimum maths requirement for either primary or secondary in my part of country.
Was working in min wage admin type job in my mid 20s, unsure of what I wanted to do and having no luck applying for graduate jobs because I lacked "experience". Couldn't afford to volunteer to gain that experience.
On a whim, I enrolled on an evening course in British Sign Language at my local college. Level 1. One evening a week. Few hundred pounds. Part funded by ILA (still funding graduates then). Course ran August to May. Just a leisure course - Didn't need to stop work.
Got my level 1 cert in BSL and deaf awareness. Went back next year to do level 2. Same set up.
Years later, I have level 6 and work full time in Deaf world. Job much better paid. Get to travel a lot.
Studying to NVQ stage was much more expensive than level 1/2 but the entry level jobs I see on Indeed.com, for support workers, TAs, deafblind guides, usually only ask for level 1/2 and sometimes specify a willingness to learn BSL.
Those kind of entry level positions aren't particularly well paid, but many interpreters and educational communication support workers start off in them, to learn/improve their BSL skills.
