Build a pro Mock Test Website

I need a website for mock tests that would focus on all the major level objective exams in country like IITJEE, CAT, AIPMT, etc. Candidates would be taking the mock test exactly same as original with the time constraint. The test has to be started at the same time for all. Major functions: 1) Candidates profiling should be there based on his/her performance 2) Automatic checking system needs to be there with the negative marking 3) Nationwide Ranking system based on the performance of candidates in a particular test 4) Security should be full proof so as to ensure tests are not leaked before 5) Tests would be done in proper pre-defined time slots 6) UI needs to be user friendly, top notch and competitve Only serious individuals/ Companies are required to bid. And please first go through the requirement and then only bid. I would not entertain general bids bidding without going and talking project specific. Seeking long term relationships.
