MVP Flutter Service Booking App

I need a seasoned Flutter developer to build an MVP that lets customers book skilled workers across several trades—carpentry, plumbing, electrical work, domestic help, elevator maintenance, CCTV & surveillance servicing, painting, and fire-fighting systems. The core build must run smoothly on both iOS and Android from a single Flutter codebase.

Essential features for this first release are:
• User rating system so clients can review each artisan
• Live tracking of each booking’s status (requested, accepted, on-the-way, completed, etc.)
• Secure in-app payments

Because I do not yet have a UI kit, I’ll rely on you to craft a clean, intuitive interface that matches standard Flutter design guidelines and keeps future scaling in mind.

When you reply, please include:
1. A short portfolio link or screenshots of any similar on-demand service apps you have shipped.
2. A clear development timeline broken into meaningful milestones.
3. Your proposed total cost for delivering the MVP, with any suggested milestone payment breakdown.

The sooner we can align on scope, timeline, and cost, the faster we can move to contract and kick-off. I’m ready to start as soon as we agree.
