I need a short consulting engagement to (1) explain compliant business models for verifiable flight reservations (no forged docs), (2) pick the right API/GDS, and (3) produce a small POC that creates a PNR in sandbox and outputs a clean PDF itinerary. Deliverables: architecture diagram, SOP, risk/TTL plan, POC code + README. Must-have: prior GDS/API experience; show proof of past PNR creation. Nice: experience with Indian payment/KYC.
