Pet Grooming Services Marketplace App

I am looking for an experienced mobile app developer or development team to build an MVP for a pet grooming services marketplace and booking platform for iOS and Android.
The platform will connect pet owners with professional pet groomers. Core functionality will include user and professional profiles, pet profiles (dogs and cats), service listings and pricing, location-based search, availability/calendar management, appointment booking, online payments, ratings/reviews, notifications, and an admin dashboard.
The MVP should be scalable, secure and designed so additional pet-care service categories can be added in future versions.
I am looking for someone with proven experience in marketplace, booking or service-platform applications. Please provide examples of similar projects you have developed and indicate the technology you would recommend.
Full specifications and detailed business requirements will be provided only to shortlisted candidates. Source code and all project-specific intellectual property must be transferred to the client upon payment, and the project must be developed using client-controlled accounts/repositories.
