Create a functional specification for a mobile app

I'm looking to have someone translate a general overview document of a mobile app into a fully detailed functional specification. This should include use cases, wireframes, flow diagrams for every possible scenario in the app. This document will then be passed to a developer for implementation and a graphic designer for design. I'm looking to have a functional specification similar to these [login to view URL] (pages 5-19) [login to view URL] (wireframes and flow diagrams) Please respond with sample specifications that you have completed in the past.
