I know it’s difficult to make a decision; especially if you receive conflicting advice.
Some schools require a degree and TEFL Cert, Others take teachers who have one or the other. Other schools consider experience as more important. They all have different requirements. However, I think it’s a good idea to do a short course, even if you choose to do a weekend course. It will help you when you start working if you have some basic skills and know how to explain language use.
One area you could consider is teaching private English lessons on a one-to-one basis. This area is more accessible to someone who doesn’t have all the formal teaching qualifications. Also some adults and teenagers need to practise speaking. This pays less than teaching but requirements for qualifications are lower. You could also find out whether assistant posts are available in state schools and universities.
You can also try applying to private language schools. Some schools provide training for their teachers, so fewer qualifications are necessary. Some large chains of schools do this.
I think there are opportunities open to you if you are prepared to consider all options.
