CAD CAM CATIA designer needed

I need someone to create some 3D objects which consists of a stack of cubes. I've attached a few examples of these stacks for you to look at. The stacks of cubes should contain between 20 and 25 cubes each and be stacked in a similar fashion to the examples attached. Additionally, the size and perspective of these cubes must be identical to the cubes in the attached examples (this is important). The stacks should have Figure A, Figure B, Figure C, Figure D, or Figure E underneath each stack. You DO NOT need to include a question above the cube stacks. The second part of this project will include a second set of all the original cube stacks you created. However, this second set of cubes will be different. The second set will have each cube painted a different color. Red, Blue, Green, Yellow, or Purple. Each cube in the stack will be colored a different color depending on the number of sides which are visible in the stack. Cubes with one side exposed will be red, two blue, three green, four yellow, and five purple. The only rule with this coloring is that the 'bottom' surface of any cube is never counted and should remain white in color. Therefore the maximum number of sides each cube can have exposed is five. The colored cube stacks (set 2) need to be in a file format that is compatible with SketchFab as I would like to be able to view the cube stacks in 3D, rotate, and view them. If you are interested in bidding on this project please do the following: Create one cube stack as an example similar to the attached examples. Color code the cubes as described above and show me that the file you created can be uploaded to SketchFab. If you do this fairly well the job is yours. I have many similar project coming up in the near future so this could be the beginning an ongoing working relationship. thanks!
