Administer deposition on written questions

I have been asked to administer a deposition on written questions and I've never done this before.  Does anyone have any tips or knowledge of this type of deposition?  Also, is there anything different that I need to do in the transcript?  Lastly, how would you handle the billing???  Thanks so much!

They stink, to tell you the truth. You're going to be provided a list of questions the attorney wants answers to. You'll write down the question as the witness reads it, and then you'll take down the answer. The whole procedure will probably be short. I know on the seldom occasions I get that type of assignment, it's usually 10 pages at most. I'd personally. I'll for the minimum appearance (bust) since that would be a greater amount than what you'll actually write.
