Visual Basic/vb.net Booking System

Hello, I need a simple project to be made in Visual Basic, using the basic command, NOT C#. This is a assignment project for my University work, I will be using your work as a basis to complete my own so it must be in very simple coding and with programmers comments, explaining what everything does. I need a very simple veterinary booking system website. There must a secure login system for the secretary of the site to be able to login and check available bookings made, and if necessary be able to edit or delete bookings. When a customer enters the website, he must able to register himself and his pet, sometimes there is more than 1 pet. Once registered he should have a login and password. Once customer has registered and logged in, he must be able to select from a drop down list an available time in the following format: 09:00 AM 09:30 AM 10:00 AM 10:30 AM Up until 5 PM. So 09:00 until 05:00 PM. And from a calendar view he can select, Monday to Friday. From another drop down list he should be able to select his chosen vet. So in the following format: Vet Example 1 Vet Example 2 Once customer has selected his time, day and vet, then he should make a booking. If a time has already been booked, if possible that time should not be available to select. If there is already a duplicate booking in the system, then an error message should appear saying "Booking time unavailable, pick another”. Once they have made a successful booking, then they should be able to view their booking. There should be some simple CSS design with a master page. PROGRAMMERS COMMENTS ARE A MUST, I NEED TO BE ABLE TO SEE WHAT THE CODE DOES. You will zip and send me all the files for the vb.net code, so I can open and view it myself in Visual Basic. Need it done within 2 days if possible.
