Minimalist Logo Design Needed

I’m looking for a clean, minimalist logo that captures my brand in a single, uncluttered mark. The overall feel should be modern and streamlined rather than illustrative or ornate. While I don’t have a rigid colour brief, black, white, and yellow appeal to me, so feel free to explore combinations or accents within that palette if it strengthens the concept.

Please deliver:
• A primary vector file (AI or SVG)
• High-resolution PNG and JPEG exports on transparent and coloured backgrounds
• A brief style sheet noting colour values and any fonts used

Let me know how many initial concepts you usually supply, your revision workflow, and an estimated timeline; I’d like to complete the project within roughly one week. Looking forward to seeing your ideas.
