for 200 USD I need a program that moves a source across the stage on Open Broadcaster Software using the OBS API

The program has a user interface and allows me to trace a path for the source that centers on top of the path and the source follows the path (the source is the name for any source ie. video, gif, image, etc. The source should be able to be scaled from small to large along the path, as well. I have other features coded up for OBS and would like some integration with my current code base. Please see the attached illustration to capture a better idea of my description. Thank you ahead of time.
