Hi, I'm from Indonesia, which makes me not from the countries you preferred, but not from the ones you are not interested in either. I do have proficiency in English. I specially studied English in one of English course in Surabaya named International Language Program whose teachers and principal were originally from Cambridge. I was once a best student in one of the grades. Starting from my first job until me recent one, my job has always been making me dealing with foreigner. Even my current position as Assistant Operational Director for an export oriented tuna and sardines canning factory, makes me dealing with US buyers and all US regulations such as USFDA regulations, NOAA, HACCP, GMP, etc.
So, I do hope we can work together. Although I still have my current main job, I do still have some spare time to really concentrate on this freelance job. Waiting for good news from you.
