Smart Car Service Advisor

I want to bring a full-featured Car Service Advisor to life and I need a developer who can guide the build from architecture to launch. The solution must make it effortless for customers to book maintenance, understand the expected cost before handing over the keys, and provide feedback once the job is complete.

Core features I need implemented
- Service scheduling with calendar views, reminders, and flexible time-slot management.
- Cost estimation that combines labour rates, parts pricing, and tax so drivers see a clear total in real time.
- Customer feedback capture after each visit, stored for analytics and quality improvement.

Key integrations
- Vehicle databases for instant VIN look-up and maintenance schedules.
- Payment gateways so deposits and final balances can be processed securely inside the app.
- CRM systems to sync customer profiles, service history, and feedback without manual re-entry.

I am open to your recommendation on whether this should be a mobile app, web app, desktop application, or a hybrid approach—whichever best balances user convenience, performance, and long-term maintainability.

Please outline the tech stack you propose, how you will handle the three integrations above, and any milestones you see as critical (wireframes, API connections, beta testing, final deployment). A short note on how you have handled similar automotive or scheduling projects will help me assess fit quickly.
