XML & API Integration for Online Travel Company (IBE)

We are an emerging Online Travel Company looking to develop an Internet Booking Engine using the API & XML provided by our supplier. We are a Sri Lankan based company, so preference will be given to anyone residing (living) in Sri lanka & bidding within the budget. Your work will be as follows: 1. API & XML integration to create a search box & call data strings from the GDS Server & present it in a decent manner on the website when the search results are returned. 2. Customer selects a flight from his list of flights, then he enters his customer information, passport information, mobile, email, address & submits 3. Customer details verified using JavaScript of any other language you suggest & then redirected to a payment gateway, if payment is successful, customer is returned back to our website & a booking reference is generated using the GDS. Customer receives an email immediately within a minute or two on the booking details (selected information), Airline PNR, Eticket number, etc. 4. Customer can use the Airline PNR & retrieve booking from our system using PNR & last name or the airline website. 5. Customer details stored in a backoffice system (credit card details not required to be stored with us). 6. Similar concept for Hotel booking as well. 7. A backoffice system where staff can view customer bookings & verify information to provide customer service & should be able to amend booking (for hotels) and change dates (for airlines & hotels), request refund (if applicable). Another single admin panel to manage staff & their access permissions. Backoffice system is mandatory for Flights and Hotels modules. 8. Apart from Flights & Hotels, we require an additional CMS where we can manually create "Custom Trips" for flight + hotel packages & upload on the website. 9. Website should be PC & Mobile friendly. HTML5, Responsive Website, CSS, Javascript, Search Engine friendly. Clean user interface & extremely user friendly. 10. Ability to add SMS gateway would be an added advantage. We are looking to develop an Online Travel Booking website. You may have a look at these websites to understand what we want. This is the main concept, customers can book Flights & Hotels from our website.

We have years of Travel experience but we are a start-up company in terms of online travel booking, therefore our budget is tight. We are looking for someone who can work with us hand-in-hand for a long term business partnership & keep all our company details & development process confidential. If we receive a decent quote from you & if you are capable of doing our project in a professional manner including the development of the site, clean & clear site with no bugs, extremely user friendly design, etc, we can assure you to be our technology provider for current and all future needs. (Our future needs would be to develop the system further, add extra modules like car, travel insurance, etc and develop mobile application for iOS and Android). We look forward to working with you, if you can confirm that you can work on our project request. We need you to do the entire project & not parts of it please. Conditions: 1. Anyone with a strong work portfolio will be given preference. 2. You MUST have experience developing Online Booking Engine for a Travel company or working with API & XML and integrating payment gateway (E-Commerce), 3. Once a project is awarded to you, we will provide you the test access data to see a sample. (This will confirm if you actually can work with the airline system). 4. Milestone will be created ONLY after checking the Test results on a live server. Thanks Good Luck! Cheers.
