Help us create a photo app (I've updated the links)

I am a construction project manager and my partner is a web-developer. We are based in Munich Germany and are in need of your support for this project. We are in need of somebody or a team that can develop an photo management and archiving app that works on Android & Apple Smartphones and Tabletts. It is called PICTOCOM. We will handle design, but you will have to program it. WHAT THE APP IS ABOUT: The construction site manager takes a lot of photos of the houses and work during the construction process because he has to document everything. It is a lot of work to export those pictures, rename them and organize them. That is why we wanted to create an app that does that for you. By selecting what you are going to take a picture of, the construction manager doesn't need to organize the photos afterwards. As they will already be in the correct folder and they will be exported to an server. PICTOCOM requirements: 1. Server and Online Web-App: 2. Web server: Apache or Windows Server 2016 3. Database: Mysql 4. For Frontend and Backend interface work with PHP 7 5. XML construction for the structure 6. Mobile Frontend Feature: 7. User Login and Logout Feature 8. Admin and User roles 9. Camera Interface 10. Temporary local save photo data on the Mobil phone 11. Automatic creation of folder structure from Admin and User account 12. Uploading from temporary photo- and file data 13. Uploading files comes to the Online Server 14. Frontend Multi-Language option 15. Multi-Language file for all words (EN-file, DE-file, NL-file…..) 16. Platform independent for all Mobile devices 17. Webbased interface will be needed for us as Superadmins and for the Users to organize/manage their pictures.
