React Native app -- 3

Hey there. I would like to develop a small platform, where users can select one or many images from their phone gallery and upload them to the backend cloud storage, and then an editor will make an edited video using those images and upload the video to the cloud server which will be shown under "My Videos" in the user's mobile app. 1. System should automatically assign the editing task to one of the editors based on the number of tasks they currently have. 2. Users must create an account, and editors will be added manually to the system. 3. Users will receive a notification when their edit is ready to download. Please tell me if you can handle this project, and what will be the cost and time required for this project. Thank you.
