STL Slicing for Side Profile Print

I need a partial vehicle body (only front section, not full body) shape sliced vertically to create a side profile print, on paper not 3d print.
Also, need the same separately horizontally. The print will be used to reproduce the object at life-size scale.

Requirements:
- STL file of the vehicle body shape
- Slice the object vertically for side profile
-Slice the object horizontally for above profile
- Ensure minimal detail for basic outline

Ideal Skills:
- Proficiency in 3D modeling software
- Experience with STL file manipulation
- Ability to create accurate, scaled prints

Looking for a freelancer who can deliver a clean, precise slice for easy reproduction.
