Development of Exam Maker

Hello, We offer practice tests to IT professionals helping them in preparation of exams. These practice tests are provided in software which is installed on the computer to give them the real testing environment before exam. Currently we have a testing engine software which is developed in PHP. We want testing engine software to be in Java. The testing software which should be followed is given in attachment. If you could develop the testing software like given in the demo, contact me to start the game. Thank you John
