Add more features to PWA mobile application

Hi, i have bought a PWA food delivery mobile application from codecanyon. I need more features to be added in-app. It is developed in React and Laravel. So only those who are experienced in these platforms only bid. Features currently have which i need to modify 1. Coupon system NOW: [ Now coupon can be mapped to all stores and single store ] MODIFICATION REQUIRED: Coupon should be mapped to Multi Stores, Coupon once per usage per user, Item-based Coupon [ How it works is, we should be able to select a restaurant inside the coupon page -- When the restaurant is selected, food associated with that restaurant should show so that the coupon can be mapped to food items we like ] 2. In Checkout page TIP for delivery boys needed. Denomination as 5, 10, 20, 30. When selected by the customer, it should be added to the total amount. It should be added to delivery boy earning as well, should show in the delivery boy app + our ADMIN panel billing 3. We admin side have an option to see Cash in Hand in Delivery collections tabs for each delivery boys. The same thing should be shown in the delivery boys mobile app also. [ So they will have an idea how much money they should deposit to the office ] 4. Pre-Order NOW: Now when a store is closed, it will be greyed out and shows closed and no orders can be made by the customers until it's open. MODIFICATION REQUIRED: When stores are closed, it should be showing a pred-order tag. Customers should be able to place orders. [ But calendar and time should be a mandatory field in checkout ]. 5. Mobile App share features [ App share to social media ] 6. Profile Edit NOW: No edit features MODIFICATION REQUIRED: Edit profile page 7. Area Wise admin/agent login NOW: Single admin login. Shows stores in all locations. Shows orders from all locations which create huge confusion when we launch a business in multi cities. MODIFICATION REQUIRED: We now have a popular location features inside. So connecting that, we need to map it to the login form of admin. [ For this feature to work I think, location field to be added inside User [ADMIN], restaurant. Need views from you regarding this feature ] Please note, we will be having a video session discussing these features after we accept your bid.
