Can i be perfect English speaker with fluent pronunciation in one month

It is possible only with your outright determination and the teacher can't help you much except motivating you to the desirable extent.It is also to be noted that reading plays a vital role in making you fluent and it is not totally mechanical.

Depends on your current level of proficiency. One month is a good time to polish your current level of confidence. A lot depends on your practice as well.
