E-commerce Brand Development: Car Diffusers

I'm launching an e-commerce brand in Australia, selling car air fresheners/diffusers that replicate the scent of high-end designer colognes. I've already sourced some basic products and blank packaging, along with a few preliminary branding and marketing ideas. However, I need professional assistance with the following:

- Logo and Packaging Design: I envision a classic and elegant style for the logo and packaging, utilizing a combination of typography and icon-based elements.
- Branding: I need help refining my existing ideas and bringing them to life.
- Marketing: Guidance on social media marketing and overall advertisements would be appreciated, with a particular focus on Instagram.
- High-quality photos of the car diffusers for online listings and promotional materials.

The ideal freelancer for this project should have experience in e-commerce brand development, logo and packaging design, and social media marketing. A portfolio demonstrating classic and elegant design aesthetics will be highly regarded.

Use the following for the logo and packaging design: black and gold. The primary target audience for the car diffusers are luxury car owners.
