Continously creating mockups

Hello friends, i need help. I Have Man.psd with this layout ;

And inside smart object i have this

I need to write script to continously search C:\Mockups\NotGenerated, if any image is on there i want to create new mockup with this PSD file and save png to ; _output folder and remove old file at C:\Mockups\NotGenerated
i tried but cant make it work.
