Flutter developer needed for AppSpot multi-business app with Laravel backend and push notifications

Hi, I want to build a real mobile app called AppSpot for iPhone and Android. The idea is that many small businesses can have their own “mini app” inside one main app. The app itself will be downloaded from App Store and Google Play. When a customer opens the app, they can choose a business/store from a dropdown or list. After choosing a business, the app should load that business’s own design, content and menu. Example: A customer opens AppSpot and chooses “BowFun ”. The app should then show: BowFun logo BowFun colors BowFun front page BowFun bottom menu BowFun contact information BowFun opening hours BowFun offers/campaigns Links to their mobile website, booking page, webshop, menu etc. The customer should also be able to switch to another business later. If they choose another business, the app should change design and content based on that selected business. The app icon and app name can stay as the standard AppSpot icon/name. The important part is that inside the app, each business should feel like it has its own app universe. Main app features The customer app should include: Business/store selector Save selected/favorite business Dynamic logo Dynamic colors Dynamic front page Dynamic bottom navigation menu Contact information Opening hours Offers/campaigns WebView/link module for mobile website, booking, webshop or external pages Push notification permission Push notifications from the selected/followed business Option to switch business Business/dealer backend Each business should have its own login. From the business backend, they should be able to manage only their own app profile. They should be able to: Upload/change logo Choose primary color Choose secondary color Edit business name Edit opening hours Edit contact information Add mobile website URL Add booking URL Add webshop URL Create/edit/delete offers Create/edit bottom menu items Send push notifications to customers who follow or have selected their business See number of followers/users A business must NOT be able to see or edit other businesses. Super admin backend I need a main admin panel for myself. As super admin, I should be able to: Create new businesses Edit businesses Delete businesses Activate/deactivate businesses Block business login Reset business password See all businesses See subscription/payment status manually See number of followers per business See push notification history Disable a business from appearing in the app Block only the business backend login while keeping the business visible in the app There should be two different statuses: Block login The business cannot log in to the backend, but their app profile can still be visible. Deactivate business The business should no longer be visible in the app. Push notifications The push system should work like this: Customer selects or follows a business Customer accepts push notifications Business can send push notifications from their backend Only customers connected to that business should receive the notification Example: BowlnFun Haderslev sends a push message. Only users who selected/follow BowlnFun Haderslev should receive it. Suggested database structure Example tables: stores id name slug logo primary_color secondary_color website_url booking_url webshop_url opening_hours phone email address is_active login_blocked subscription_status created_at updated_at dealer_users id store_id name email password role is_blocked created_at app_menu_items id store_id title icon type url sort_order is_active Menu item types can be for example: home offers contact webview booking webshop external_link offers id store_id title description image start_date end_date is_active app_users id device_id push_token selected_store_id created_at updated_at store_followers id store_id app_user_id push_enabled created_at push_notifications id store_id title message sent_at sent_by status Important The app should not just be a simple WebView app. It should be a real app with native structure, dynamic design, dynamic bottom menu and push notifications. Some pages can open inside a WebView, for example booking page, webshop or mobile website, but the main app navigation and business profile should be controlled by the backend. Technology I am open to suggestions, but I think the app can be built with: Flutter or React Native for iOS/Android PHP/Laravel or Node.js for backend MySQL/MariaDB database Firebase Cloud Messaging for push notifications I want to start simple with an MVP, not a very complex system. The first version should include: Main app Business selector Dynamic business profile Dynamic bottom menu Business login Super admin login Offers Opening hours/contact info WebView links Push notifications Block/activate/delete business from admin panel Please give me a price and timeline for this MVP.
