Secure Rental Boyfriend Booking

I am building a web platform where visitors can schedule and pay for time with a “rental boyfriend.” The core feature I need you to deliver is a smooth booking flow tightly coupled with a payment module that supports Bank Transfer as the sole payment method. No other payment options are required right now. Because real money and sensitive data are involved, I want the payment workflow wrapped with advanced encryption plus an active fraud-detection layer. Think along the lines of TLS 1.3 everywhere, tokenised transaction references, and heuristic monitoring that flags suspicious patterns before they settle. I’ll also need clear audit logs so I can respond quickly to any chargeback or compliance enquiry. Front-end and admin usability matter too. Customers should be able to pick an available time slot, confirm the fee, and receive immediate on-screen and email confirmation once their transfer is verified. On the back-end, I need a dashboard where I can view upcoming bookings, mark transfers as cleared, issue partial or full refunds, and export basic reports. Deliverables • Responsive booking interface (mobile-first preferred) • Secure Bank Transfer payment gateway with advanced encryption & fraud checks • Admin dashboard for booking and payment management • Deployment instructions and short technical hand-over guide Acceptance criteria 1. All sensitive data is encrypted in transit and at rest. 2. Fraud-detection triggers can be demonstrated with test cases. 3. A successful end-to-end booking takes under 60 seconds on a 4G connection. 4. Code passes a quick security scan (e.g., OWASP ZAP) with no high-severity issues. If you have solid experience implementing secure payment flows—especially for transfer-based systems—and can work fast, I’d love to review your approach and timeline.
