Could one of the English experts help me?

What is the meaning of 'the immediate posting of the check'?

And I think there are some mistakes in the text:

- here are the info --> here is the information

- You have to choose from the above courier company --> You have to choose from the above courier companies

Hey Mesud,

I have tried to translate it, but there are some parts I couldn't understand too, for example, I couldn't understand the meaning of the sentence,

"we want to inform you that we need a copy of your identity in attached form as we have inquired the mailing information and here are the info."

Postalama bilgisini tahkik ettiğimiz için kimliğinizin bir kopyasını ek olarak göndermeniz gerektiği konusunda sizi bilgilendirmek isteriz ve bilgiler şu şekilde:

As=due to the fact that

Ah I really didn't get it. It's so hard to understand, i have translated into turkish but my sentences are so different than yours, i guess my translation will be rejected.
