Three versions of one application for hotel booking needed - one for iPhone, one for Android and one for Symbian (S60 5th edition).

Please look at http://www.hotzebra.com (still a beta version). We need mobile applications for the three mentioned platforms that would copy the functionality of this page. Changes in design and layout would be necessary, functionality should be the same. The applications would communicate with our server to receive all data and handle bookings. 

The project will come to an end when the applications are published in the respective app stores.

Previous experience with mobile applications is necessary – please list specific references in your bids.

Additional Info:

The apps will communicate with our server using data format suggested by the programmer (JSON, XML, CSV, ....). The search will be submitted from the app to the server, and the server will do all the search related logic and return ready data to be displayed. Information from our server will include all necessary data, such as availability and prices. 

Therefore the task of the programmer is mostly to create the new format of the applications (some work with graphics is expected), submit queries to our server and subsequently display the returned data in proper format. 

The map part of the apps will use Google Maps API. Here, the communication is between the apps, Google and our server. 

A small part of the communication between the apps and our server must use SSL (submitting the credit card number and personal data). 

In general, the apps should include all features currently available on the web site. Some restrictions in the comfort of the use (when compared to the full web-site) are acceptable. 

The web has three main pages (main page, search results page and hotel page) this - should transform in the apps as follows: 
The apps should have three screens: 
1. Search (criteria) 

a. Where (including suggest functionality), when, activities, search on a map 

2. Search results 

a. Once a hotel is clicked-on on the search results page, the hotel is page is displayed with detailed information on dates and prices. After a choice is made by the user, he can place a reservation by submitting the necessary data. 

3. Map 


Features that can be omitted: 
- Flexible dates search 

- Bookmarking hotels 

Added feature: 
- "Around me" search
