1,960 Apparel Mockups

I have lot's of mockups that I need made, but they are all very simple. There are 70 images in total, that will all be placed on the clothing garments (in the same EXACT place, with the same pixel height). There are 7 different products, but each product has multiple product colors.

For example:
Polo Shirt 1 - 4 color variations
Polo Shirt 2 - 6 color variations
Shorts Style 1 - 4 color variations
Shorts Style 2 - 3 color variations
Shorts Style 3 - 2 color variations
Hoodie 1 - 5 color variations
Hoodie 2 - 4 color variations

All images will be provided, as well as high res blank product images. I just need someone to place all the images on the blank product mockups, and save them as separate files for each product/color - so you will be delivering 1,960 separate files. The files do not need to be high resolution. I prefer a png with a transparent background.

The provided images may, or may not need the white backgrounds removed - I will try to remove any backgrounds from the images I provide. The images I provide will need to be properly resized. All images should be 60 pixels in height, and all need to be placed in the exact same exact spot for each product and color. For example - all the polo shirts need to have the image in the same exact position with the same height, etc.
