CLONE FLIGHTS SEARCH ENGINE

I am looking to clone a website called "www.momondo.com". It is a search engine that searches airlines throughout the world for the cheapest flights. I am looking to have an exact clone of this website with all of these features that the current site has. It is only a search engine and not a booking engine, so no payments would be taken online. It would need to search all of the airlines that it does. I honestly dont know how this is done, whether they have a deal with each airline or not. This is what I need you to figure out. If I see anybody just bidding on this project without looking at the proper brief, I will just ignore it. I want a PM from all interested bidders showing me similar work they have completed, if they think they could complete it, ideas and of course how much they think it would cost. I dont expect this project to be cheap but I dont want ridiculous bids as I will just ignore them. The idea of the website would be to keep it completely free and not have any ads or anything. I may call on you to send me a full brief before I select you fully for the project. Please review the whole website here : [login to view URL] I greatly look forward to your bids. Many thanks
