Modern Logo Design for Marketing Agency

I'm launching a new digital marketing agency and need a clean, modern, and professional logo to represent the brand. The logo should look sharp both online (website, social media) and in print (business cards, proposals, presentations).

What I’m Looking For:
- A minimal yet creative design that communicates trust, growth, and professionalism.
- Scalable files for use across web and print (SVG, PNG, JPEG, PDF, etc.).
- Variations: full logo, icon-only (for social profiles), and black/white versions.
- Branding guidance (recommended fonts and color codes to match the logo).

Requirements:
- Proven experience in logo/brand identity design.
- Strong portfolio (please include links or samples).
- Ability to provide 3–5 unique concepts with revisions until final approval.
- Clear communication and fast turnaround.

Nice to Have:
- Experience creating logos for agencies, startups, or service-based businesses.
- Ability to deliver in multiple formats (including vector files).
