Where can I find a clone script of kayak or triprow or asiarooms etc?

I want to check out a script similar to kayak or flighthub or expedia. However I am not interested in allhotels combined type affiliate model.
Also looking for a script similar to hotels.com, asiarooms etc which allows users to submit reviews and pictures. Something that can be used to create a trip advisor type destination mini guide.
Can anyone please point me in right direction where to start?
Thanks in advance.

 

Please let me know if you find anything.

 

I dont think that scripts like this are open source.

 

I am still looking so if anyone is familiar with setting up of similar site please let me know

 

You can do it for free with wordpress using this plugin:

Let me know if you need someone to work on it
