Modification of Full Mobile Application

I am looking for a skilled developer who can help me modify my full mobile application. The application is currently built on both iOS and Android platforms. Specifically, I need the following modifications to be made for the application, the application consists of 3 apps and one website: 1. Users Application (App). 2. Vendors Admin (App). 3. Application Admin (Website). Users Application: 1. Add OTP Mobile number verification for only 6 countries (Bahrain, Kuwait, UAE, Saudi Arabia, Qatar and Oman) phone numbers for registration. Currently OTP is not available. 2. Hide wallet. In the current mobile application, it has the feature to deposit money which I want to hide, it should be only to make reservation with payment. 3. Hide withdraw requests. Currently, since the users are depositing money in the application, they can request for withdrawal, I want to hide this feature too. 4. Only 2 languages Arabic and English (Arabic text will be provided). In the current application, there are multiple languages, I want it to be only English and Arabic, and Arabic I will give the text, I don't want the translated text. 5. Remove (Make Payment) and change it to (Confirm Booking) and Change (Pay Now) to (Place Order). Those are extra pages since I will remove the paying feature from the application, those will be no need for them. 6. The customer can add notes for the booking. Currently, no notes are available, however, those notes shall appear to the Vendor admin once the order has been placed. Vendor Admin: 1. Notification for the salon for the order status (Pending, cancelled, etc.). Currently for order status the vendor is not receiving notifications. 2. Hide Edit bank details. This feature to be hidden since there will be no payment feature in the app. 3. Adjust timings to be weekdays from Sunday to Thursday and weekend from Friday to Saturday. On the current application, the weekend is considered on Saturday and Sunday, I want to change it to Friday and Saturday. 4. Minimum one service image in Add Services. When the vendor is adding services to application, It asks to upload 3 images, I want to make it only one image to be uploaded. 5. Hide wallet. Similar to the user application since no payment will be done through the app. 6. Hide payouts. Similar to point no. 5 Admin Panel: 1. Discount codes to be only to a specific Salon. Currently, the discount code is applicable to all the vendors, I want to make it specific and applicable to only one vendor.
