Add drag/drop Image Reorder to Existing Vue2 App

I have an existing VUE 2.0 web app that shows uploaded images. I'd like for the user to be able to drag images to reorder them. The callback for drag/drop would have to include info to update database with appropriate order. Sort Order is a field on the recordset. The existing app has buttons to move 1 spot forward back or send to the front/back but the end user wants drag/drop reordering. Max spend on this project is $130.
