One-Time Booking System Build

I’m launching an online “rental boyfriend” service and need a focused booking engine to power it. The platform’s core is simple: guests should be able to pick a date and time, confirm availability, and lock in the reservation—no recurring or repeat-series bookings, just single sessions every time. Key pieces I want delivered: • Clean, responsive booking flow (desktop & mobile) that collects the guest’s details, shows real-time availability, and finalises the slot in one step. • Automatic SMS notifications fired on confirmation, reminder, and cancellation. I’m open to any reliable gateway (Twilio, Nexmo, etc.) as long as messages arrive quickly and logs are easy to review. • Admin dashboard where I can add or block out times, view all bookings in a calendar view, and manually trigger SMS updates if needed. • Basic safeguards—double-booking prevention, error handling, and a straightforward cancellation window. If you have an existing framework or prefer to build custom, just outline your stack and how you’ll keep the code maintainable. Payment and other add-ons can be stubbed for now; my immediate goal is a solid one-time booking workflow with dependable SMS alerts. Happy to answer any technical questions before you dive in.
