Banner design

I am looking for a freelancer to design a custom banner for my product or service advertising needs. The banner should be bold and eye-catching in style. I require a custom size, so the freelancer must be able to accommodate this. Ideal skills and experience for this job include graphic design expertise, experience working with Adobe Photoshop or Illustrator, and an eye for detail. Additionally, the freelancer should have experience in creating effective ad campaigns and a strong portfolio showcasing their previous work.
