Mobile App Specs Document!

I'm looking for an experienced system analyst to write a requirements document for a mobile app for a school application. We would need to talk and I will describe you the app, and you will create the doc that will allow a developer to develop the app.
This is a few days' work assuming you are fully available.
Please send a link to a previous doc you've written.
Please start your msg with the words "I will create a great doc!"
