Festival Brand Asset Creation

I need a designer to create cohesive brand assets for an upcoming festival. We already have some brand assets and a defined look and feel, but require additional elements to complete our branding.

Required Assets:
- Banner Design
- Social Media Graphics (for Facebook, Instagram, Twitter, LinkedIn)
- Speaker Treatment
- Letterhead

Ideal Skills and Experience:
- Proven experience in creating festival or event branding
- Strong portfolio showcasing social media graphics
- Proficiency in both modern and minimalist designs
- Ability to work with existing brand assets and integrate new designs seamlessly

Please provide samples of previous work and a brief overview of your approach.
