我想問”希望這次和貴公司會作愉快”英文點寫

希望這次和貴公司會作愉快 :
I hope we will have a successful co-operation with your Company!
(We will not say 這次 in English, because it may mean we did not have a good co-operation last time)

"希望這次和貴公司會作愉快
I hope that it will be a fantastic co-operation with your company.

And hope that you will be happy.

希望這次和貴公司合作愉快
愉快is pleasurable from the noun pleasure
貴公司is a formal and respectful way to address a business partner

可以客套地說：(敝公司)希望這次和貴公司合作愉快
We wish that our co-operation with your company this time will be a pleasurable one.

被選答案內把愉快譯成successful，是風馬牛不相及。
有時successful(成功)人士也不愉快。
翻譯最基本也最重要的是保留原文內的意思，不要把自己的意见加入譯文。
