Master Course Scheduler

I am looking for quotes from programmers who can build an automated master course Scheduler for U.S. middle and high schools (grades 6-12). The program should allow the user to upload csv files that will list: course names, teachers assigned to each course and those teachers period availability, classrooms with number of seats and periods available, etc, and individual student requests. The program should them generate an efficient master schedule that places each course in the appropriate periods to meet the maximum number of student requests. It should print the master schedule and completed individual student schedules. Ideally, I would prefer to have this as a program that would run on a desktop (Mac or PC) rather than as a web app.
