Student results Create Read Update Delete (CRUD)

Our primary school needs an application which can CRUD student results.
It has to comprise the following functionality with an emphasis on security.:

1. There is an existing mysql/ database with student numbers and student names
When the app.is ready for delivery, we only have to change some connection parameters

Security
2. Due to the nature of the data that will reside within the system, the application must provide a very coherent en dense security system, mysql_real_escape_string and htmlentities and maybe other security measures are required as well as best practices to defend from common web hacking attempts
3. It is required to write an encrypion method to store and fetch data from the Myssql database. We dont want to store plain text in the database.

The application has three stakeholders:

a. Parents/Caretakers of the student:
when their session has been set, due to a correct login procedure,
they can view the results for every subject for all of their own children

b. Teachers
When their session has been set, they will be able to perform CRUD operations on all data in relation to results or grades of students. So it is no problem when a teacher assigned to group A, alters results for children that reside in group B.

c. Application administrator
Some flags and parameters are not writable for teachers, but only for application admins.
For instance a backup procedure should be issued by an application admin.

If you dig this project and are willing to fullfill it, we would like to have contact.

-Of course we want you if you have good programming skills and a reasonable knowledge of defending techniques to protect our data.

-We want to make your source code availabe as open source on a public repository like bettercodes or github after delivery of the application.
