Banners & Posters Designer Needed

I'm looking for a professional graphic designer to create a series of banners and posters for advertising a product/service. These designs will be used in both online platforms and physical locations, so they need to be versatile and impactful in different contexts.

Ideal skills and experience for the job include:
- Proficient in graphic design software (Adobe Illustrator, Photoshop, etc.)
- Experience in creating corporate-style designs
- Understanding of both online and offline advertising needs
- Ability to create visually appealing yet professional designs
- Excellent communication skills for understanding project requirements and feedback.
