Attendence Caluclator

I'm looking for someone to build an Attendance Calculator for my business. This project requires tracking student attendance and the ability to generate graphical output about the data collected. I need the system to track the time of day of employee attendance, as well as the frequency of employee absences from the workplace. Scheduling also needs to be tracked. Depending on the generated results, I want the system to generate graphs, spreadsheets or charts to help me visualize and analyze the data that is retrieved.
