What's the best practice for importing the first questions and answers?

Question

Hey,

I started a new Q2A site. I got some one to prewrite me 200 questions with 3 answers for each question.

I'm interested in registering 100 users, asking those 200 questions and answering them over time.

Here's the order that I'd like to do it:

1. 3-6 (random number) new users a day that ask questions
2. 6-18 (random number)  answers per day from random users

What's the best practice to do it that it will look the most naturally?
