Logo Line Refinement Needed

I need a quick polish on an existing logo. The only task is line refinement—no color correction, no background removal. I’ll provide the artwork in PNG/JPEG format, and I’d like the lines cleaned up so they appear crisp and consistent at any size.

Deliverables:
• Refined logo with smooth, even lines returned in high-resolution PNG
• (Optional but appreciated) a vector version if you can easily generate one

This is a straightforward job, so please let me know how soon you can turn it around and share a brief sample of similar cleanup work you’ve done.
