Animate Multiple Logos

I have some logos I would like animating for my website. These should be supplied as SVG files so I can give them to my developer to upload.

I will provide you with 10-12 coloured logos.

The task is:

1. Make all logos greyscale
2. Make all logos same proportions
3. Animate

See example of how it should look here: https://clay.global/ (see Google / Facebook logos, half way down the homepage) - I want it to be exactly like this!

To be completed within 24 hours.
