I am looking for someone to provide a mobile / tablet app that acts as a children's book.
24 illustrations can be flipped through one at a time.
Text is shown off to the side in one or two languages.
Audio files play upon flipping the page that have the corresponding narration for that page.
The app should have settings allowing the user to select 1 or 2 languages out of a total of 10 languages available.
If two languages are selected, audio for both languages will play sequentially on each page.
The app will be a free platform for reading this particular book series.
The app will need to allow in-app purchases in order to download new books when they are released.
Administrative web interface allowing the author to create new publications to be made available within the app.
Illustrations for the publication will need to be uploaded through this interface.
Text for each illustration will need to be input.
Audio files (mp3s) will be uploaded for each page through this interface.
Author will need to manage and edit existing titles through back-end interface.
Please provide similar experience.
Please provide a realistic estimate for a project of this magnitude.
