Mockup Scene Creator Web App

We need a mockup scene creator web application similar to [login to view URL] I will provide all the graphics you need for all the objects. We will take care of the user management. What we need you to work on is a frontend web application where a scene can be created by arranging different objects on the canvas and then the canvas downloaded as a png image or editor-state json. There will be a system for admin to be able to add new objects (foreground, accessories, plants and background). Pls go through the reference web app ==> [login to view URL] If this is something you can do, let me know the cost and timeline as well as your plan. Thank you.
