Luxurious Stationery & Packaging Redesign

I'm looking to upgrade my current, simplistic logo and product packaging through a color scheme, typography, and graphic illustration update. I'm aiming to transform the design to reflect a more luxurious and premium style. This transition should seamlessly translate across to new stationery items, including brochure, letterhead, envelope, and visiting card. I will need mockups for these items.

Ideal Skills and Expertise:
- Proven experience in luxury branding and product packaging design
- Expertise in typography and color psychology
- Proficiency in creating corporate stationary items
- Ability to create mockups for a clear representation of the end result.
