Change the colours on an existing After Effects video

I have a promotional video which can be seen here: https://www.youtube.com/watch?v=voGHOyEXoyY

It was created in Adobe After Effects for which I have the source file.

We are essentially changing the colour scheme for the company and I will therefore need the colours on the video changing.

I am looking for someone who is willing to discuss the colours before changes are made and who will be willing to make revisions based on the final result.

All content is to remain the same, it's only the colours that need to be changed.

If you have any questions then please message me and I will provide as many answers as possible as quickly as possible.

Thanks.
