Convert STL. and VPF. Utensil Design to STEP. Format

I already have a complete STL/VPF file of a single-piece plastic utensil that is headed for injection-molding, and I simply need it converted to a clean, feature-recognizable STP/VPF-STEP model. No geometry changes, drafts, or other tweaks are required—just an accurate translation that preserves the part’s dimensions, wall thickness, and smooth surfaces so my mold-maker can open it without errors.

You are welcome to work in SolidWorks or Fusion 360; I can accept the native file as a bonus, but the primary deliverable is a validated STEP file that imports into SolidWorks 2021 without healing.

When you respond, include a short but detailed outline of how you handle STL/VPF to-solid conversions for injection-mold tooling (surface reconstruction, checks you run, etc.) and the approximate turnaround time. That proposal detail will help me choose quickly.

I will supply the STL/VPF as soon as we start, and I expect the finished STEP plus a quick note confirming that you verified integrity, scale, and watertightness.
