Developing a Web-based Student Management System

We require development of a simple, but efficient student management system that we can install on our server and access over the internet at any time. Some basic administrative functionality it needs to have is: 1. Entering demographic details of students 2. Entering Details of the program the student is enrolled for, when student was enrolled etc 3. Uploading of student documents such as certificates, transcripts, etc 4. Complete Fee management 5. Search function to be able to pull out any kind of report. 6. Single registration number should be able to pull out all information about a student. 7. Should be built in a way so that additional functionality can be added with ease. Will provide detailed information later. Freelancers who have experience in developing such systems must only Bid. Thanks.
