Modifications to Quiz module

I need the following modifications in the Quiz module:

1.Option to display a configurable number of questions per page. In its current form, you can show one question per page.

2.Administrator should be able to add more properties to the Questions in the database.

3.Administrator should be able to set up a query that is executed before displaying the Quiz page. This query will fetch questions from the Database. Essentially, instead of displaying the questions sequentially, or in a random order, we want to be able to query the questions from the database and display to the user.

4.We will develop cues for the questions and store them in database.

5.For each question, the user should be able to view the cues. She should be able to ask for more cues or decide to take no more cues.

Pls respond with prior experience with module development and a quote.

Pls contact me if there are questions.

Regards.
