poster making

I am in need of a creative and eye-catching poster for promoting an upcoming event. While I do not have specific images or text in mind, I have a general idea of what I am looking for and am open to the designer's creativity. The poster should be a standard size of 24x36 inches. Ideal skills for this job include graphic design, marketing, and branding experience. The designer should have a portfolio showcasing their previous work in event promotion, and be able to provide multiple design options for me to choose from. Timeliness and communication are also important factors for this project.
