Hi
I'm native Italian, I'm more than fluent in English and I have a bit experience on language classes and teaching, I just recently start to teach to my Thai wife Italian with very good results, I'd like to try with you, we can have a chat and see what are you looking and what I can offer to you.
I see you asking for 40h/week but I'm quiet confident that 14-16 hours are already quiet a lot, plus I guess you're speaking Portuguese so it's gonna be quiet easy to teach you because grammar between the languages are quiet similar.
Please feel free to contact me anytime regarding this matter, I can be very flexible on everything.
Regards, Claudio.
