Creating a questionairre in PHP

Hi, I am developing a quiz kind of website. I am looking for someone to work on the below requirements. 1. We should be able to add Questions with multiple choices,affirmation questions (true/false) in the admin page for a particular topic There can be 'n' number of topics and we should be able to add questions to add selected topics 2. Once the questions are added, these questions should be visible in the user interface. 3. Once the user selects answers for all the questions and click on submit, it should validate the answers and provide a result ( like 60/100) Also it should show all the correct answers, wrong answers, incomplete answers and the user should be able to view the answer for a particular question. Budget 50 - 100 USD. Interested people, please bid. Thanks Alwyn
