Modern Business Logo Design

I'm looking for a modern-style logo for my new business LEEMONT Fire & Electrical who will be operating in the commercial building industry in Australia. We are uncertain if our logo should be a brand symbol or industry specific as the company may operate in other fields in the future. Whatever colour it ends up being will be our theme colours, prefer blue/green/grey tones. attached chatGPT versions we have liked so far, but open to new options. Would like the final design in both JPEG/PNG and vector formats (AI/EPS/SVG).

Ideal Skills and Experience:
- Strong portfolio of modern logo designs
- Proficiency in vector graphic software
- Creativity in color selection and design concepts
- Experience with brand identity development

Please share your portfolio and estimated costs and timelines.
