Query for Buying Paid Version

Hi Team,

I have tried the free version of the Quiz Maker and find it best according to my needs. Now, I am interested to purchase your quizmaker plugin. Before I buy I have some questions as follows. Please get back to me with the answers that will help in decision to purchase.

1. Can I display Google Ad with each Question? If yes then How?
2. Can this google Ad be reloaded with each questions? That is if I have 10 questions then I can have 10 Ad impressions.
3. Is there any restriction I can provide to a custom User Role?
4. Can I also have TAGS associates with the questions?
5. Is there any discount available for the Business version?

Thank you
