Prototype Development - 3D Car Design

I am looking for a professional 3D designer to create a design for a car front and rear bumper using Blender. The design must be based off 3d scannings of the original parts (will be delivred as mesh). The design shall be done as a "sleeve" fitting over the original bumper. I will need the design for both the new sleeve as well as the "cavity" inbetween the new sleeve and the original bumper (to allow for production of foam to fill the cavity).

I will provide:
1. Scans of original parts
2. Photos of intended end design (for inspiration - there is a reasonable level of creative freedom)

Examples of "input" and "output" can be seen here:
"Input" (original bumper design): https://www.carandclassic.com/car/C1734378
"Output" (your bumper design): https://hanwells.net/vehicle/bentley-turbo-rt-mulliner-in-hanwell-london-81c0fdf9-aed7-4a0f-a237-f159a76f5050

I will need:
1. Print ready files (which means the parts may have to be cut into sections - this must be done so it is "invisible" and there must be connectors between the parts, allowing for a strong and seamless connection)

Will likely need an iteration or two to nail the design.

Key requirements:
- Expertise in using Blender for 3D design
- Ability to design fully functional mechanisms
- Experience in prototype development

Please provide examples of your previous work in your proposal.
