Boyfriend Rental Booking Platform

I’m building a web-based service where clients can browse available rental boyfriends, see when each is free, and lock in appointments on the spot. The heart of the project is a smooth booking and payment flow: a user picks a profile, checks a real-time availability calendar, reserves the desired slot, and immediately receives bank-transfer instructions to complete payment. Core needs • A responsive front-end that showcases profiles (photo, bio, hourly rate) and displays up-to-the-minute availability. • A secure back-end that manages bookings, prevents double-slots, and issues confirmation notices the moment a transfer is logged. • Payment integration limited, for now, to bank transfer; however, the architecture should allow easy expansion to cards or PayPal later. Tech stack is open as long as the calendar updates in real time (WebSockets or a reliable polling strategy are fine) and data remains consistent under load. Clean, well-commented code and a short hand-off guide are part of the deliverable so I can maintain and extend the platform myself after launch.
