Bold & Colorful Flyer and Poster Design

I'm organizing a promotional event and I need an eye-catching, bold and colorful design for flyers and posters. The target audience is the general public, so the design should be appealing to a wide range of people.

Key requirements:
- Strong graphic design skills
- Experience in creating promotional materials

Please include examples of your previous work in your proposal.
