Develop portal for me

What i want is a windows based captive portal system for a university. The admin will be able to register students and staff. the admin will be able to determine the daily duration that students can have on the internet The staff will have higher bandwidth speed over the students. Students that want higher bandwidth speed will have to purchase vouchers for the higher bandwidth. The admin can also be able to create events account where the event participants can be able to use the captive portal. After the development I will expect you to guide me on how to install the system on my laptop and make it work. Thank you
