How do I write a letter to the Depa

How do I write a letter to the Department of information in Chinese, I am interested to learn Chinese language with your institution.
I would like to know the student and school expenses. If it's not bothering me, want you to send me all the information.
And I'm going to start learning as soon as possible.
