Design a sleek and professional business card for a reputable real estate agent specializing in representing both buyers and sellers. Drawing inspiration from the clean and modern aesthetics commonly associated with successful agents, the card should exude trust and expertise in the real estate industry. Highlight the agent's tagline of offering low rates with higher quality than the industry standard. Incorporate elements that convey a sense of luxury and sophistication, while maintaining a timeless and elegant design. Include the agent's name, title, and contact information prominently, along with services offered for buyers and sellers. Utilize a classic and professional color scheme, such as navy blue, charcoal gray, or deep green. Consider incorporating subtle design elements or motifs commonly found in the branding of well-known real estate brokers. The overall design should be minimalistic yet impactful, leaving a lasting impression on potential clients.
