518007 GradeBook Mac OS iPhone Application

Need a Mac Application to accompany a iOS application. The app is a grade-book for students to keep track of their course grades and assignments. The mac app needs to handle course objects that contain metadata and an array of assignments. The functionality for calculating the grades and similar tasks is already done as it will be the same as the iOS app. I would like a developer to put together the user interface views and hook them up to my data structure. I will need the source code as I will be responsible for future updates and implementing a lot of the functionality. I will provide a design of how I want it to look so this should be a fairly simple project for someone familiar with iPhone development.
