I have gone through your requirement and understand that,you are looking for highly skilled, qualified, and experience (Android ,iphone /ipad) Mobile App with development API web services where admin can manage the app from backend development team for your project.
I would approach your project by starting with wire frames and getting the design completed, before starting the actual development phase.

Looking forward for your Response.
