Batch create t-shirt mockups from 300 different designs

Job ID: 37465779

Budget: €250 – €750 EUR

We have 300 designs we have created and we need them applied on t-shirt templates in different colours.
Designs are ready and t-shirt templates in different colours are ready.
This is a batch job. So this needs to be done in photoshop or other batch system where the 300 different artwork is applied to the 15 different colours. They are all applied just at the center on the front of the t-shirt, all in same place.

Process is:
1. Download art work (most in PSD) links provided (links are provided in google sheets to each artwork)
2. Apply each artwork on to t-shirt templates in 15 different colours (all look same except colour - art work all in same place.
3. Change artwork colour (one colour) to gold, black and white and apply also the same way.
4. The output files are PNG files for our website. And the files should be named with structure - name of t-shirt colour, name of artwork, etc. we have samples/instructions for that.

This way each artwork will be available in 15 different colour t-shirts and then also 3 different fonts on each colour.

The total output files will be ca 14.000 files.
This is however batch work. Most of the work is downloading the files and preparing the batch setup.
