Respected Mr. Abaday,
This is TG Shakthi from Chennai India, and I read your project specifications in full,
Here is my understanding of your requirements,
1. We need to provide the Technical documentation on how to implement the project and its functionalities. This is like a complete project plan and Data flow diagram to show how the project will proceed in estimated time frame.
2. Provide a list of best developing websites who have previous knowledge in Travel Related websites,
3. Get the proposals from the Companies and submit them. Also give a writeup on why the companies listed are best in terms of ranking and so on,
Notes :
We ourselves are developers and we are proficient in Travel related web developments. Before going deep , we need to get a login from major Travel Booking Agents like "Amadeus", "Worldspan", "Travel Port" etc. and to get a login you need a IATA licence from the Goverments (Depends in the country where you want to get the IATA Code" ).
And once you get the login from a minimum of 3 GDS we need to code it in our system to get the base fares and Taxes based on the country.
The best development for the booking engines that talk to the GDS is Java, Servelets and topped on by dhtml and jquery . These open source are the best to develop with security and tamper proof transactions between the clients, users, GDS and the administtrators .
Will be greatful if given an oppurtunity to work on your projects,
Best regards,
TGS
