Android/iOS Mobile App

We are seeking an app to be developed for both Android and iOS systems for an adult entertainment services. Throughout the following rundown, our workers would be referred to as "models" and our customers as "users." The app would need to facilitate both audio and video calls between the models and users as well as text messages. These services would be paid for via the purchasing of credits on our system. Payments via credit cards should be facilitated as well as bank transfers and cash app payments specific to different countries. Having never had an app developed before, I would refer to it as a 4-sided system: 1. The Public Side The public side should have just a "Sign-Up" and "Login" buttons. Snap shots of our service should be included as an "automatic slider." Standard features such as a reset password, contact us, etc should also be displayed here. We would like a "Sign-Up as a Model" button should also be included. 2. The Model Side Our "models" should be able to upload pics and videos in a free section as well as a purchase section as well. They should also be able to set their own prices for each service, ie, the audio and video calls as well as the pics and videos in the purchase section. 3. The User Side The user should be able to purchase credits. Place audio or video called, purchase content, all depending on their available credit. They should be able to "favorite" models and set limits on their credit purchases such as "Max $50/day." They should be able to set a username/screen name and search for models using various criteria. They can also leave comments on the model's page. 4. The Admin Side. The admins should be able to calculate payroll automatically for models, have a data base for distributing payments. They should be able to delete accounts or help with any customer issues. All audio and video calls need to be recorded on the admin side for reasons of customer abuse or. threats, etc. Admins will also be responsible for activating model's profiles when they pass our criteria such as age, etc.
