iPhone/iPad booking application for travel agency

We are looking to create a reservation app for the iPhone, for our travel agency. This app will be very much similar to that of skyscanner currently available via app store in terms of functionality with a few added extras. The user will need to be able to makes their choice of destination date of departure, date of retune and other trvel related information, such. Via e app , once they click in search, the app will then link to our online booking engine(third party) and will display the results of the seach with in a browser with in the app it self. Please bear in mind that as the current booking engine is a third party product and a off the shelf product, we do not have access to any web services and /or api data. The app will also need to have two extra functions, one we would need to be able to send push notification of any special deals which we may have, and two be able to link to another app called checkmytrip (again currently available) via app store, so that the customer can view their itinerary through the external app. ## Deliverables As mentioned above we do not have web services and or api for our current booking Internet search engine, however I have been told that it is possible to write to the page with the information provided on the app but we would not be able to retrieve data from the site, hence why we need to have the search results and the actual booking it self to be carried out with in a browser in the app itself, so that the Internet site allows the booking to go ahead.
