I’m expanding goaship.in to let visitors book both domestic and international passages in one smooth flow. The current sandbox from India Post has proved the mechanics work, but its tariff table doesn’t match the rates I want to charge, so the core requirement is a booking module that: • recognises whether an enquiry is domestic or international and applies my own price table accordingly, • walks the user through passenger details, sailing date / route selection and payment hand-off (the gateway hookup is already live), • finishes with an automatic, nicely branded confirmation email for every successful reservation. You’re free to build a single responsive page that branches logic internally or two distinct pages—whichever is cleaner in code—but my admin side must let me maintain those domestic and international prices without touching source files. A lightweight dashboard, CSV upload or even Google-Sheet pull is fine; I just need control. All integration details for the existing India Post sandbox and current site stack will be supplied right after kick-off. Deliverables are the working booking page(s), editable pricing rules and the confirmation-email trigger wired up in production.
