Minimalist Logo & Letterhead Design

I need a fresh, minimalist logo that features my company’s initials and pairs perfectly with a matching letterhead. The overall look should rely on cool tones—think confident blues, calming greens, or elegant purples—used sparingly so the design stays clean and uncluttered.

Here’s what I expect:
• A primary logo in vector format (AI, SVG) plus high-resolution PNG and JPG exports
• A simplified, single-color version for stamps or small-scale use
• A professionally laid-out letterhead template delivered in editable formats (DOCX or AI) ready for both print and digital correspondence

All files should be fully editable, with fonts either embedded or linked, and color values clearly defined in CMYK and RGB. Once final files are approved, please include any usage guidelines that ensure the brand stays consistent across future materials.
