Arrange schedule

If you see any mistakes in the following sentence, can you correct them for me? Thanks in advance.

Hi XX,

How are you doing? I am very happy to hear from you again!

The schedule you arranged for me is great and I can't complain about it.

Regarding your first question about my availability in the aftetnoon during the pre-course, ( or regarding your question if i can teach afternoon classes during the pre-course), I am available. And as for the second question if I can help you find more teachers, give me sometime. I will try to contact some of the teachers I know and let you know later sometime.

I again appreciate your work for me and see you soon.
