Conversion of basic iOS to Android

We have a large number of iOs apps that need to be converted to Android. All apps are universal. If you complete this on time and on budget, then you will get a long, steady stream of work. To begin with, it will be a simple iphone children's book that uses standard page flip and contains about 30 pages with audio. No overly complex features. Please provide a portfolio of work with an explanation of what you did on the projects. I am looking for a long term relationship with a person or company that is very responsive, knows Android inside and out and is comfortable enough with the iOS environment to accurately understand the apps we provide. Since our clients are all in the entertainment field, trust and reliability will be key for this relationship. I look forward to reviewing your work.
