3D Car Model Sculpting

I'm looking for an experienced digital sculptor to combine two existing car models and make several modifications. The final output should be in OBJ format.

Requirements:
- Combine two preexisting car models
- Modify the combined model:
- Resize certain parts
- Add new details
- Smooth transitions between models

Ideal Skills and Experience:
- Proficiency in 3D modeling software (e.g., Blender, ZBrush)
- Strong attention to detail
- Experience with automotive models is a plus
- Ability to deliver high-quality, clean OBJ files

Please provide a portfolio showcasing relevant work.
