Looking for help to install a booking engine for car rental on wordpress site - urgen

Hi,

I’m after some help in installing an ajax booking engine on a wordpress site , the engine is provided by car trawler.com. I have a pdf showing how it should be done but it is beyond me i’m afraid. It says that it is an ajax online 3 step booking engine.

An example of the booking engine - rhinocarhire.com

thanks
