Malware / Spyware for Android Mobile Project

I rented a Ready-to-use Android Mobile spyware app (details of the app will be given later) Need an expert to create a small script that will ONLY install the Ready-to-use spyware app on my mobile without needing physical access. The freelancer is encouraged to use WhatsApp messaging to make this happen either by sending a picture or video message with the script embedded inside the picture or video.
