Develop a Mac Application

I am a teacher of English and I have always wanted to create a quality app that can be useful in my classes. It 's a thanksgiving gift to my students and colleagues as well and it will be free for years to come. I decided to reach out to Professionals with exceptional creativity and positive attitude to make this app exceptional. The pay will and should always be fair. Come on guys , let's make it happen. The app will contain but not limited to : Student version / Teacher version It will cover 10 aspects of teaching Most of the work will be putting together excel based sheets for the teacher to fill in ( Questions and Multiple answers, where the teacher ticks the right answer and the results of the class will show instantly in green and red + percentage ) The file will later be sent either to the teacher's email,the students' or the class log) I have a detailed plan because that's what I do everyday: I use apps to teach.
