I am looking to be certified to teach english abroad (outside the USA). There is a ton of info out there - too much that contradicts itself - so here I am.

1) I have a bachelor of science in Biology, a minor in Geology, and I have worked as a teacher, National Park Ranger and outdoor educator - with all age groups. What is the best course for me to take in order to get a decent paying job where I do not get worked to death - TEFL / TESOL or CELTA?

2) Any opinions as to the TEFL course offered in Buenos Aires, Argentina?

3) Job opportunities after you complete the course? Can you make enough to live somewhat comfortably and save a little?

4) Would anybody recommend elsewhere to take the cert. course and then potentially work after?

Thanks for (hopefully) answering some or all (again, hopefully) of my questions.
