Flight comparison script

We need a script that will screen scrape about 5 external websites and get back info for flights according to the clients requested criteria. The script should then display the results and provide affiliated links wich the customers can follow to reserve the flights they choose directly with the airline. Its operation should be similar to [login to view URL] but it will search for a lot less results. Pretty straight forward for someone who knows what to do… We do not mind what kind of technologies you will use for the development of the project. Please only bid if you are familiar with the above and fully understand what needs to be done. Only real bids in money and time NO PLACEHOLDERS please. Thanks alot
