Android and iOS app for social networks advocacy

We already own and run a system in Laravel and we need to make a iOS and Android app with some functions on the Apps, below a general description of needs, the complete needs and details well be explained after initial contact: We need to add some functions to it, using our already database users (login using same user/pass as our Laravel system) and ability to recover password using their registered email: 1.- Add Menu Section for Social Advocacy 2.- In this section the Menu options will depend on the user level (admin, editor, operator, etc.) 3.- The admin can: A) Create custom posts with text, url's, image(s), video or audio for social networks: FB, TW, LKDN and Email, the system needs to adjust the text total character according to each social network, as well the image/audio/video size to each social network, giving the option for the user to resize, crop, move the media. They can assign the permission to modify the text of the post (not the media) or not to the users. B) Create group of users, with filter based search he can select in bulk users to add to Custom Groups where the admin will give a Name to the Group and assign users and ability to remove users from groups with filters as well delete Groups. C) The admin can schedule any post he have created to be shown in the other user levels Advocacy Section to a total users or Group users in a schedule Example: from 15:00 January 30 of 2023 to 14:00 January 31 2023. D) The admin can send push notifications to Android and iOS apps, pushing with a custom text/image and deep link to a Post who wants to share with the users. E) The admin can edit, delete, duplicate any post he made. F) Know, edit, delete, the points earned by each user (explained more after) G) Have a metrics dashboard where he can see the total shared posts by day, week, month, year, filter by Social Network, Group, User. 4.- The Users can do this: A) Click to Share the Posts that the Admin user sent to them, with one click needs to be easy and fast to share the content shared by the Admin to their personal Social Networks, they can choose the network where they want to share it. The text can be edited by the user if the Admin gave that permission on that shared post, if not, the shared post needs to be exactly as the Admin created. B) Earn points by each real shared content (each unique post to each unique social network) C) Know the points they have earned until today, and see the Posts they have effective shared in their networks The system needs to work using high security O-Auth for social network access. IMPORTANT: - We don't pre-pay, we work on result basis, work done, payment done. - We can split in 3 milestones maximum. - We DON'T work with agencies, sub-hirers, we need to work with REAL DEVELOPER of the work. - This is a long-run project with more functions to be added - We don't work in hour-basis, we work only for project budget, you need to understand well what you accept and what you can really do (or not). We will give the pre-designed templates and/or create needed ones specified by developer.
