I've developed School Management System for colleges here in Nepal. Some of the core functionality that I can offer you are:
1. Website Frontend and Adminpanel Design
2. Administration control on website design on header, footer, sidebar, contents, galleries & so on
3. Online teacher notes and assignment
4. Student and Teacher Register/ Login .
5. Real-time Student attendance record-keeping and monitoring .
6. Online Result Publishing and Downloading PDF file.
You may share your requirements of the website. If I get this wonderful opportunity, I'll put my best effort to complete the task respecting the deadline.
Thanks and hope to hear from you soon
