Build a software solution that searches online travel reservations websites

We need a simple piece of software developed and built to search all travel/booking/reservations websites for airfare and hotel pricing. The scope of this can be discussed as an initial search of travel booking websites must first be developed to generate a list. This system is required to be used by a travel agent to minimize the time taken to search for cheapest fares and to maximize efficiency. They system interface needs to have all the typical search functions. For example: Travel Dates and flexible date searches. Locations (From To) Flight routing options ie. one-way, return and multi-destination/stop-overs. Passenger numbers Other search options: ie. direct flights, refundable flights only, preferred airline, travel classes. Needs to be able to search how many seats have been offered Needs to be able to search how many bookings of the same type being searched have recently been sold. Needs to show booking fees. Further specs can be provided and confirmed prior to build and refined during testing before 'go live'. The output of this system needs to show summaries of all search options including prices. The system needs to be able to sort the options/outputs by a number of types ie. price: high-low, travel time/duration: longest-shortest etc... We would like the system to be able to process the booking with the selected service provider (travel website). Or at least a link to the actual reservation on the website so the booking can be made. This spec can be further discussed and clarified. User Interface needs to be simple for the end user. Must be compatible with Ipad. Time frames for delivery can be discussed, I would prefer a quality product. Out of Scope: I may also need a Travel website built in the near future so there may be more in it for you if job well done.
