Flex 3 - Simple online student attendance/reports system

We are seeking the services of an experienced Flex 3/PHP/MySQL developer to assist with the development of a simple online tool that will enable 3 different user groups to share information pertaining to the attendance of students to school and work experience locations. The system is to be used by the students to keep track of where they need to be on any given day (school, work place etc), by Mentors (users that are located at the work experience location that students will be attending) and by Administrators (who can create user accounts for students and work experience Mentors). The main functions of the system are to enable the student to have an up-to-date reference of where they need to be on any given day (school, work, assignment due date), to enable the student to read feedback from the Mentor or System Administrator and to be able to post feedback back to the Mentor and Administrators. The system will also enable Mentors and Administrators to share information about the student - but not with the student. The system is to be based around the idea of a shared calendar where both the Administrator and Mentor users can use the calendar to set dates in the students calendar. This project must be completed on or before January 7, 2010 - so only about 10 days from now. I have attached 2 PNG files - one shows a basic site map of the project. The other is a top-level view of the data and relationships for the 3 user groups. I will also provide full screen by screen layouts of the entire system to the successful applicant before commencement .
