IOS Mobile App from Scratch

General information for the app: This will be the first simple version of a new app about food and recipes
Kind of development: New app from scratch
Num. of web pages/modules: 5
Description of every page/module: The app consists of a Home Page with Login/Registration via Facebook, a page with a search engine and filters, a page to show results and a page to view the detail of a recipe.
Please read carefully the document attached with specifics, description and desired flow of the app.
Description of requirements/features: The mobile app will call some REST API to retrieve/access data.
Interfaces for these APIs are already in place and any useful information to access them will be provided.
Extra notes: I have the logo but not the graphic. Suggestion to improve the quality of the app, or people with high graphic skills to draw icons will be appreciated to choose the perfect candidate.
