Korean question?

[Nabi]

제가 부산 갈 때 만나뵙고 싶습니다.

내가 --> 제가 formal expression
우리 만납시다 --> 우리 is probably from "let' us" of 'us' doesn't add any meaning. '만납시다' is commanding expression of "let us meet" where you can use it, if you are of same age. If you are addressing it to a older person, it is not suitable to use commanding expression to him/her. You may express your wish to meet up. Like "만나뵙고 싶습니다", wish to meet you.

If you want to say, "I'll arrange a meeting," you can say, "제가 자리를 마련하겠습니다."
