請問這樣寫可以嗎 ? Contract has been sent to Ann by Courier today, and will call courier to pick up the signed contract .?

The contract was sent to Ann by courier today. Once it being singed, we will call courier to take it.
用現在完成式，不得使用today明確時間
will call 的主詞不是contract,所以顯然缺主詞

The Contract has been sent to Ann by Courier today-------just put forward; submit; present perfect tense;
and will call the Courier to pick up the signed Contract (when honoured and drawn up to) to the stated authority.-------the full complement.

The unsigned contract (待簽字合約) has been sent(已被送出) to Ann(給 Ann) by our courier (由我們的快遞員,Courier用大寫則用意不明，是人名還是公司名?), and he’s been charged with the responsibility to pick up (他被賦予收回) the signed contract(簽字完成的合約).

1.如果contrast已經寄出的話就用had been
2.and will 少了主詞
