Sabre API Flight Hotel Engine

I need a lightweight OTA front-end built around the Sabre API that lets users search flights and hotels on the same website, see live availability, and then hand the booking off to me for manual ticketing.

Core flow
• Home page with a combined flight & hotel search panel.
• Flight search must offer three date modes: exact date, ±1 day, or ±3 days.
• After a traveller chooses an itinerary or property and submits their details, the system should:
– Create a Sabre PNR in my PCC.
– Store the quoted fare in the PNR.
– Fire an email (or webhook) notification to me containing the booking summary so I can verify everything and issue the ticket offline.
No online payment gateway is required at this stage.

Please use Sabre’s latest REST/JSON services where possible; fallback to SOAP calls if a feature is missing. A clean, responsive UI (plain HTML/CSS/JavaScript or a light framework like React) is fine as long as the code is easy for me to maintain.

Deliverables
1. Source code for the search and booking modules.
2. Simple front page template wired to the search logic.
3. Documentation: setup, environment variables, and Sabre credentials required.
4. Brief hand-off call or video explaining deployment and PNR flow.

If you have previous Sabre or other GDS experience, let me know—speed of delivery and API accuracy are key for me.
