3D Design of Ocean Waves

I am an artist, looking for someone to help me. I need a realistic 3D model of ocean waves. The idea is that I will have this file printed with a 3D printer to produce a base on which I will paint my artwork. The 3D Design should be 50cm x 50cm, with the depth varying from 5mm to 30mm, based on the movement of the waves. If this can work I want to do some much larger ones. So hopefully this will be a relationship.

Photo reference below. But as a base for a canvas... Imagine looking down at about 45 degrees at an almost but not quite calm sea, rippling with waves in various directions, taking a photo, and somehow managing to get a cast of that image. That's the idea. Who can help!?
