Android app -- interactive kids book

I need coding and graphics for interactive kids story book. Every story would be made of 16 to 20 scenes, and on every scene would be one or two interactive objects. For start, there gonna be 5 storys. If coder is able, then later, app should be ported to iOs. Sound gonna be handled separately, but it is gonna be coded in this project. Native english readers needed for synchronization of characters voices.
