Full Brand Identity Development Based on Existing PNG Logo (Vectorization + Production Variants)

I already have an existing company logo concept created in PNG format (attached).
I am looking for a graphic designer to professionally vectorize and refine it, preparing the essential versions needed for business and production use.

This is NOT a request to create a new logo from scratch.
The goal is to improve the existing concept and prepare clean, professional files for practical use.

Scope of Work:
professional logo vectorization (editable vector files)
refinement of the main logo version
preparation of key logo variations:
horizontal version
vertical version
icon/symbol + logotype separately
monochrome version
black & white version
negative/inverted version
simplified version for:
embroidery
engraving
laser cutting
technical marking
Final Deliverables Expected:
AI
SVG
EPS
PDF
PNG
JPG

with full commercial usage rights and source files included.

Industry:

Industrial refrigeration / HVAC / automation / industrial technology.

Preferred Style:

Clean, modern, technical, professional, and premium-looking.

I prefer freelancers with experience in branding for technical or industrial companies.
