1) First, we should determine the number of students who would be interested in spending an academic year at your school. Once we know the numbers, we can organize a student exchange program for next autumn.
2) OK
Could you please check these last two sentences, again? Thank you.
1) On one hand, I think it would be best to organize a student exchange program for next autumn and, on the other hand see the number of students who would be interested in spending an academic year at your school.
2) By the way, how do you plan to organize the email partnership?
What do you think of my proposal? I would like to start next week with it.

I didn't pick up on this before, but you should use "on one hand ... on the other hand" when you are setting up a contrast (opposing ideas). Your first sentence here, however, is setting up a two-step process: 1) find out how many; 2) organize the program once you know if there are enough people interested.
