Abstract animation

Hi there, I'm looking for a 3D animator who is able to do a 20-30s looping animation with a glass design similar to this: https://www.youtube.com/watch?v=5YfAgFCUtVQ or the squares in the attached image.

Please share with me the following:
- Fees (inclusive of 3 rounds of revisions)
- Turnaround time for 1st draft and subsequent revisions
- Relevant portfolio works
