make sliders and banners for my website

I am looking for a skilled designer to create sliders and banners for my website with the purpose of enhancing aesthetics. The ideal candidate should be able to work with a specific color scheme that I have in mind and create custom sized graphics. The design style should be clean, modern, and visually appealing. Experience in graphic design and proficiency in Adobe Photoshop or Illustrator is required. The project should be completed within a reasonable timeframe and revisions may be necessary.
