Firstly, I want to say that I could speak Arabic too, seeing that you come from Iraq, that would probably be beneficial in case you need help explaining more complicated stuff, but of course we speak mostly and mainly only English.
So, I've studied English, both American and British, for so many years and have tutored students and supported an assistant English teacher who needed help, I've also written my own short story and started a new novel recently.
I set the available hours just as an average, but if you need more I could offer many more hours.
Looking forward to your reply.
