Van rental driver service in Taipei?

My family about 5 others are coming, I would like to take them around visiting. Is there some van rental service with driver in Taipei?

I once helped a friend to rent a car for his family from this number:
Try (02)250-54188
after some searching, I think the name of the company is:文華客運有限公司
tourbus.org.tw/pages/index.p … e=&Ipg=pro
At that time he rented a car, 7 person capacity, from Taoyuan airport to Gongguan for NTD1300 one way. They also lend it per day, different cars capacity that you can choose.
Another friend of mine also rented 20 persons capacity bus to take his family around Taiwan for couple of days, 9 persons in total.

And this is another rental car company that usually my company calls for business trip use:
whitehouse.com.tw/

You can choose one of them or call both and choose one that is cheaper if you care about the price.
