Pal,
It's no big deal as far as your command of English is good enough to be accepted as an English teacher's generally!
Go get your hands on a few English grammar books to get familiar with grammar terminology and read briefly about the teaching methods. You'll be on a roll when you get yourself in action.
You have a pretty good background to be a very successful English teacher!
Good luck
