Edit automation

Hi

I'm looking for a software that would allow me to edit videos with preselected motives. It's hard to explain so I'll give you an example of the workflow I imagine the software should provide.

I've got great footage say of a beach house with green posters on its walls.. Now I'd like to add customers photos to those "greenscreens", easy on edit, but time consuming and it should be automatized in order to get this profitable... second there is a tv in a beach house, and when we cut into the material that's on telly, it should be customers own material.

so this is what the software should do:

1. I'll insert a file with photos and videos named correctly to the software
2. the software takes the photo by name and video by name and places them on right places to the video
3. the software automatically then creates a ready video file and sends it to where ever i need it to be sended (to desktop, or to cloud or somewhere...)

Is there a software that does this? Can I like preorder something from the edit software? what? who? where? What to read and what to google? youtube tutorials for dummies that don't know what to look for? :D

Hmm. I hope I used terms that are even close to actual language.

Thanks,

Antti.
