Looking for advice

Currently teaching in a small town in Spain, and I have a contract until June. I’d like to try a bigger city I’m not sure of what to do afterwards, I have level 3 Tefl + a degree. From what I’ve found jobs in major cities in Spain and Latam seem few and far between. Should I return to college to do a masters, or try to find a job in a bigger city? (I like Spanish speaking countries)
