plane ticket metasearch

I need an application that allows users to search for airline tickets across multiple sites and display results in a unified view. It should search and parse the data from each site, remove duplicates, and display to the user the results. Feature Requirements Search UI User must be able to specify Departing Airport/date/time, Arrival Airport, Returning Date/Time, number of tickets. Results should display: Airline Name departing airport departing time arriving airport arrival time numbers of stops Duration of flight lowest price found (best deal) Site the lowest deal was found on link to access the particular deal on the site List of sites that had the same flight, and their individual prices, links to the flights on each site Note that the results should be displayed as they are found, and not once the parsing of all results has been done. User should be able to sort results on :Price, arrival time, departure time, Airline name, stops, Site name (sorting is optional feature) The application should assist the user with finding the appropriate airport. The list of airports should an updatable file (xml). All sites use the same abbreviations for the airports. It must search at least three of the following sites: orbitz jetblue united expedia travelocity hotwire I have very limited budget so please PMB if you think you can do it cheapper by cutting any features or by following different architecture. ## Deliverables Technical Requirements The UI is not important, it will be rewritten. The importance is the backend part which queries the different sites and parses out the data. It should be written in C# or C++(speed is very important) and must be a component which can be used in VB.net/C#/C++.net. It should be modular, fast, and extensible. The business logic for adding a new site to search and the parsing for that site should be stored in a .dat or .xml file (or .net dll) which can easily be updated without having to install the whole program again. The goal is to use it for a Windows Application, not a web application. 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No GPL, GNU, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the coder's Seller Legal Agreement). ## Platform windows
