Hello there!
Here is an experienced teacher of English as a second language.
With 2-8 $ per hour you will probably find yourself confronted with someone who can speak the language, but doesn't have the experience needed for such an intense course.
2 hours per day is a lot, so I am guessing there is a specific occasion at hand.
If you send me the details, we can trim the course to suit the occasion.
Of course, the grammar stays the same, but the vocabulary varies largely when the target language changes.
