Answer 1

Hello, welcome to our company. My name is xxx. It is my responsibility to show you around. You've all worked very hard. Please follow me. This way, please. May I introduce a few members of our company to you, this is the Chairman of the Board, Mr. Liu, this is our General Manager, Mr. Ma, and this is Mr. Shi, our manager. Please take a seat. Have some water. Help yourselves. If there is anything you want/need, feel free to call me.

Answer 2

这显然是负责接待的人在引进来宾，在一段时间内分别说的话，因此不连贯的。

Good Morning/afternoon/evening, welcome to our company. My name is xxx, I am in charge of the reception of you.
Please follow me.
This way please.
Please allow me to make some introduction to you, this is Mr. Liu, the chairman;
this is(在介绍时，手指向被介绍人时this is也可省略） Mr. Ma, the general manager; this is（同前） Mr. Shi, the manager.
Please come in.
Sit down please.
Please have some drink.
If you need any help, don't hesitate to ask me.

大家辛苦了

If you are talking to foreigners, there is no need for such expression (in English).
You only say this in Chinese to Chinese (people).
