OK guys, we can close that topic, we found a native to help us IRL.
Thanks for your answer, Chinoise, however, to post the French letter would just have extended the process, because if I can't write in English really well, I still can recognize the meaning that the automatic translator suggested for my French sentences and most of them were correct. (even if I noticed I did the corrections too fast and there were still too many mistakes as there:
I was able to notice it during a language study holiday in Australia, or I acquired a good level of English, when I lived with Japanese, Korean and Thai for 6 months.)
Thank you really much anyway, enjoy your day/night
