Animate a loop video for me

We are creating an art installation which will mimic mining crypto currency. On computer screens, we will need to display an animation in a loop which will represent a computer based mining process (e.g. matrix-like code or similar). It should also display coins which need to bear our logo. The mood should be quite dark and mysterious, very technical. The video should be around 20-30 seconds long but the loop should be seamless. Please send over your portfolio for us to evaluate if you have done something similar before.
