Minimalist EFR Monogram Design

I need a sleek, high-end monogram built around the letters E F R, finished with the full name “E. F. ROFF” directly beneath the symbol. The mood is modern and minimalist, in a pure black-and-white palette that feels exclusive rather than stark. Clean geometry, balanced negative space, and perfect alignment are essential so the mark looks equally strong on a business card, website header, or embossed packaging.

Please supply:
• The primary monogram and the stacked lock-up with the name below, delivered as editable vectors (AI, EPS, SVG) plus high-resolution PNG.
• Black-on-white and white-on-black versions.
• A brief style rationale and any font details to keep future brand assets consistent.

First concept files within three days would be ideal, with refinements after feedback. Mock-ups that show the logo in context—foil stamping, stationery, or digital screens—will help me visualise the final result.
