App development

Hi, I need cross platform app with following features: 1. A internal browser which supports downloads and saving the downloads 2. Sharing the saved file 3. Code should load webpages from local storage. 4. The database options can be : a. Server DB b. Emergency db [login to view URL] db by syncing with the server db in case of emergency. If internet is switched off, program should automatically upload the non-synced db files into server’s DB. 5. Access to Camera to provide pics to program. Program may have a camera application to capture pics and save it in a local folder called “Photos” inside the app and support file browse on the web-script’s browser to upload images to the software. 6. Ability to download pdf files when generated , shared to other programs and store a copy of it in the “Downloads” folder inside the app’s folder. We should be able to share these pdfs whenever we want and also be delete-able. A new sub- folder should be created each day and named day wise. Files should be stored day-wise in respective folders. The same is applicable to “Photos” folder. Sub-folders should be deletable. 7. API to print the pdf generated 8. A native module to create doodle in artboard and save the same through an API interacting with the web script 9. A from above artboard with space to enter ID number and API to import/call the associated data upon entering ID number and display above artboard in the form like auto fill. 10. Save the artboard with form in pdf file in a particular module 11. Print the artboard and form 12. Host more than one databases if needed. 13. Firebase notifications to a native app which yet to be made 14. If you know codeigniter, you can make APIs on your own. I will give you extra fund for that 15. If you know codeignitor, we will need to edit the script and integrate firebase. Also, we need to add some forms for notifications. I'll give you additional funds Kindly mention the platform, time and budget required. Quote reasonable prices as there is competition when I am posting here
