Two-Sided Tasking Platform Development

I want to build a two-sided marketplace where people can post tasks/jobs they need help with, and other users can browse available tasks and offer to complete them.
The platform should include:
User registration and login
Two user types: Customers and Taskers/Workers
Customers can create a task with a title, description, photos, location, date/time and budget
Workers can browse and search tasks by location/category
Workers can submit offers/quotes for tasks
Customers can review offers and choose a worker
In-app messaging between customers and workers
Notifications for messages, offers, bookings and task updates
Profiles with ratings and reviews
Booking/task status tracking
Secure online payments
Platform commission/service fee on transactions
Payment release after the task is completed
Dispute/cancellation system
Admin dashboard to manage users, tasks, payments, commissions, reviews and disputes
Website plus iOS and Android apps
Clean, modern and simple design
The design, branding and UI should be original, not copied from another existing platform
