Innovative marketplace ios and android app

I am looking for a mobile app developer which is ready to create the front/back end of a home service marketplace. This team needs to have an expert in the api search. This app will be similar to soomgo and thumbtack which need api for payment, gps, escrow, time tracking, background check ( chechr), customer service, ai chat, dispute ( fairclaims), scheduling etc...

Providers special features:
-SMS bot notification to potential providers online
-ai generated automatic quotes based on projects inputs

Clients:
- Projects linked with potential providers from same gps localisation,reviews,price
- Group deals ( create or vote ) for group projects which can be sent to providers for biding
- Rewards and benefits api
