Manipulation of 15 images to produce 75 mockup on images.

I have 15 photos of my product but would like a graphics designer to manipulate and crop composition of them to yield 75 visuals of the product placed as a mock up in other like real life scenarios.

Guide: Clean and minimal compositions.

Please see the product images in the link below

The device is a Ultra Violet sterilisation device used for sanitising devices, such as phones earphones, keys ID cards etc.
The photo mockups need to showcase the product in different environments, eg; inside backpack for travel, on the kitchen counter, office desk, doctors desk, in children room etc. The idea is to simulate the product placement in real like placement.

The photos are to be used on Instagram/Facebook/LinkedIn posting

In your proposal response please share similar graphical work you have done, that involves photo manipulation and product mock up placement.
