Android/iOS/Web application - Handyman services

I want to make an application and web portal similar to
https://www. homeadvisor.com
https://www. taskrabbit.com
for Android, iOS and Web

2 Mobile applications:
* Customer application
* Handyman/worker application

Customer application (Android/iOS/Web):
• Sign up screen
• Able to search, find and show handyman in a list with summary.
• Able to see the details if a result is selected.
• Able to hire and place an order on a worker based on availability.
* The app will send details to the worker and wait for confirmation with a final price.
* Able to accept final price from handyman/worker.
• Able to pay with a third party payment method or cash.
• Able to close and give a feedback/review

Handyman/Worker Application
• Able to sign up and add a profile with the categories where he wants to be found with tags or keywords, rate, etc.
• Able to setup an schedule with availability.
• Able to block periods (unavailability) on schedule.
• Able to receive orders with the details from customer and then proceed to confirm with final price.
• Able to see a payment/account portal with orders and revenue

The project must include design, backend services, DB and scripts ready to deploy.
Java backend services preferred, but not required.
Cloud ready services preferred, but not required.
