Looking for 3D motion designer/animator

We want to create kind of a ''satisfactional'' gif for our ''Get a quote'' form on our new website. For one of the segments, we'll need to insert a gif. It will mean that filling of the form is almost over, just 2 quick final questions left. For the GIF, we think to recreate the movement which could be found in the attachments. But with better quality. We've already designed 3D environment and cube in our brand colors. It can be found in the attachments as well. Please provide a quote on this task and include your relevant animation portfolio. After this project, we'll already have the next one which we'll offer to the freelancer. Thanks!
