Teaching English in Santiago, Chile

I am an American living in New York City interested in moving to Chile in the next few months. I was hoping to find a position teaching English in Santiago. I do not have any teaching experience but plan on taking the TEFL certification. I have run my own business for the past five years and have been working in sales/recruiting for the past thirteen. Any advice out there on how to find a good job? Can I meet monthly expenses with teaching? Thank you!
