回信的英文翻译？（如下)

非常荣幸能收到你的来信，很抱歉这么晚回复你，也希望这并没有影响到你的安排。
It is my great pleasure to receive your letter. I’m terribly sorry for my late reply, and hope that it wouldn’t affect your arrangement.

我想我可能在16号以后就会有空,这个时间可行吗？如果可以，我想在开始工作之前，去一下厂里当面了解一下你所期望我所负责的工作。

I think I will be available after 16th Apr. Is it acceptable according to your plan?  If it is ok, I would like to make an appointment with you to visit the factory before start my work for well understanding of my work range.

不知你何时有空会在大陆工厂，能让我知道几点会更好以便我能准时到达，谢谢。

Would you please let me know when it will be convenient with you in the mainland factory? Then I can be there in advance, thank you a lot.

如果贵司已经有合适人选，不再需要我，请知悉一下，谢谢。

If there are some other proper personnel, and no need for me to come, please also take the trouble to let me know. Many thanks.  

Remember me to Mary and two of your cute babies!
