Airtasker-Style Task App Development

I want to launch a task-marketplace similar to Airtasker that ships on iOS and Android at the same time, so a single cross-platform code-base is essential. Users must be able to create an account instantly with Apple, Google or Facebook, post a job, receive bids, choose a worker, pay safely, and leave feedback once the work is done.

For the first milestone I need a fully functional MVP that covers:

• Task posting with budget, deadline, photos and real-time bidding/chat
• User profiles, verification badges, star-rating and review history
• Secure payment integration with hold-and-release logic (Stripe, PayPal or your proven solution)
• Social sign-in/out plus email option
• Push notifications for bids, acceptances and task status

React Native, Flutter or a similarly modern stack is fine as long as it delivers native-feeling apps and smooth App Store / Google Play submission. Clean, well-commented source code, basic unit tests and clear build instructions must be handed over on completion.

When you reply, let me know:
• The framework you’d choose and why
• A realistic timeline to reach a test build
• Links to any marketplace apps you’ve already shipped

Wireframes and branding are ready; once we lock the approach I can share them so development can begin right away.
