Website & App Service Booking

I’m purchasing a ready-made platform and need it turned into a clean, intuitive website with a companion mobile app. The core task is to let visitors buy or book services directly from their phone or browser. When a customer books, they must be able to pick the exact service they want along with an available date and time; the system should confirm the slot instantly and update availability in real time.

I already have the platform licence lined up, so your job focuses on front-end build, integration, and making everything feel effortless on both desktop and mobile. If you prefer React, Flutter, Swift/Kotlin, or a solid no-code stack, let me know—what matters most is a smooth, user-friendly flow.

Deliverables
• Responsive website fully connected to the booking engine
• iOS and Android apps published to their stores
• Admin access for me to update services, prices, and time slots
• Email/SMS confirmations and calendar sync for users
• Short hand-over guide so I can manage basics without coming back to you each time

Acceptance criteria
• A new user can land on the site/app, choose a service, see real-time availability, and complete a booking in under two minutes.
• All bookings instantly reflect in the admin dashboard and block out that slot for others.
• Apps pass App Store and Google Play review on first submission.

If this sounds like your kind of build, send a brief outline of your approach, timeline, and the tech stack you recommend so we can get started.
