XML Airport Transfers Script

I am looking for a web script that I can place within a wordpress page. This script will use xml / soap and allow customers to book airport transfers online, paying via [login to view URL] or [login to view URL] (TBC) The script will generate a price based on the distance (road distance not straight line) and a price per mile + a booking fee and profit margin. The script will send booking confirmation to relevant partner so if transport is from Edinburgh then script will e-mail Edinburgh Taxi Partner. The script will allow the booking of inbound, outbound and return journeys. Inbound = From airport to hotel Outbound = From hotel to airport Inbound Return = From airport to hotel then hotel to airport Outbound Return = From hotel to airport then airport to hotel If customer selects inbound journey they then select airport. From their select all taxi partners covering that airport will be chosen. A quote is calculated and the cheapest taxi partner's price is displayed. If a customer selects an outbound journey then they enter a pickup postcode. That post code is then checked against the ones covered by the taxi partners. If that post code is covered then the taxi partners covering it will be chosen and quotes calculated. The cheapest price is then displayed. If we do not cover area e.g. London then an apology message will be displayed. See a simple powerpoint for details: [login to view URL]
