Language exchange - Japanese and English

Hi, I'm a Japanese postdoc and looking for English native speaker who wants to learn Japanese. I'm gonna teach you Japanese and you're gonna teach me English (daily conversation). One of my current ideas is to have a system where, for example, if we have a two-hour lesson, the first half of the hour is spent speaking only in English, and the second half is spent speaking only in Japanese. I also have a wife and two kids (they are all Japanese people) and my wife is also learning English, so if you like children or you have a family, I welcome the idea of having you come to my home, or meeting with your family members to conduct lessons. If you are interested, please contact me.
