Logo Redesign for a Luxurious Appeal

I'm looking for a professional designer who can revamp my brand logo to give it a more upscale, exclusive feel. The changes will primarily focus on the logo elements/design, where we will:

- Incorporate a new icon or symbol into the design
- Include a tagline or slogan

The redesigned logo should convey a message of luxury and exclusivity, so prior experience in high-end brand design would be a plus.
