Private English classes for General & Business English

I am certified TEFL teacher and I offer classes for general and business English. My mother tongue is English but I'm a B1 in Spanish. I'm interested in teaching teenagers and adults. I teach conversational English, business English & grammar-intensive English. 
I currently work as an English teacher giving in-company classes for project managers, department heads and executives. 
I charge 18€/hour for 1-to-1 classes. 
I charge 14€/hour per student for group classes. I only accept cash and the payment will be given at the end of every class. 

I have a flexible schedule. The classes will be in your house, your office or a cafe.
