Modern Logo Design Needed

I need a fresh, contemporary logo that instantly signals my brand’s personality. Clean lines, balanced typography and a memorable mark are the priorities, so please keep the style strictly modern—no vintage flourishes or heavy ornamentation.

Here’s what I’m after:
• One primary logo concept refined through a couple of revision rounds
• Final files in fully editable vector format (AI / EPS), plus high-resolution PNG and JPG with transparent backgrounds
• A one-color and black-and-white version for versatile use
• A quick reference sheet summarising the chosen fonts and colour values for future consistency

If you can show relevant samples that prove your modern-logo chops and outline how quickly you can deliver first drafts, that will help me lock this in. I’m ready to get started as soon as I find the right designer.
