Did he contact you, or did you contact him first? If he contacted you out of the blue, likely a scam. Also, he doesn't seem to know what town you live in, sure giveaway, though not mentioning it could just mean it's a given, hence it doesn't need to be mentioned. However at the end is the dead giveaway, a request for "All" of your personal information, from address to full name to phone. This is not normal for an ESL teaching job, and the hefty offer of $45 an hour is likely just a butter up to get the info. This is a common scam to get personal information for identity theft. It also reads like a Nigerian scam letter, and a chain letter, these are all signs of a scam.

It also makes no sense as this is an International board, and he is moving to a country where the main language is English. It would be easier to wait until you get there, or to go onto an "American" website where teachers and tutors advertise their services, not an international one. Use common sense and it's easy to distinguish the scams from the non scams.
