I changed a few things from my previous mail. Could you check grammar and punctuation, Writeacher? Thank you!

1) I suppose you received the remaining balance because my bank has already taken the money from my bank account. 2) However, I would be grateful to you if you let me know about that all the same.
3) In my previous post I wrote that on 15 August I was coming to pick up my children from your school myself.
4) As I'll be busy at that time, I would like someone from the school (??) to accompany them to Heathrow airport.
5) Furthermore, I wonder if it were possible to receive the prospectus about your summer course as well as a list of things they should bring with them as soon as possible since I will be leaving London in two weeks.

1) I take it you received the remaining balance because my bank has already taken the money from my bank account.

2) However, I would be grateful to you if you let me know all the details.

3) In my previous post, I wrote that on 15 August I was coming to pick up my children from your school.

4) As I'll be busy at that time, however, I would like someone from the school to accompany them to Heathrow Airport.

5) Furthermore, as soon as possible, I need to receive the prospectus about your summer course, as well as a list of items they should bring with them since I will be leaving London in two weeks.

Here is the corrected version of your email:

1) I suppose you have received the remaining balance because my bank has already deducted the money from my account.
2) However, I would still appreciate it if you could confirm that for me.
3) In my previous email, I mentioned that on August 15th, I would personally come to pick up my children from your school.
4) However, as I will be busy at that time, I would like to request someone from the school to accompany them to Heathrow airport.
5) Additionally, I was wondering if it would be possible to receive the prospectus for your summer course, as well as a list of things they should bring with them, as soon as possible. This is because I will be leaving London in two weeks.
