c++ is a complicated language, but i do not but i do not believe that you would need a teacher for it - a book is sufficient for most people, as to teachers of c++ in general i have never come accross one, with the exception of people who work in universities, as it is the kind of thing you learn when you do a computer science course
i would recommend buying a book - i used Mike McGrath's C++ in Easy Steps, it's a simple book but the examples in it are very good at explaining the point
