Creative Web Graphic design

I am looking for a creative web graphic designer who can help me with designing promotional material for my social media channels. I have specific preferences for color schemes and visual themes that I would like the designer to incorporate into the design. The ideal candidate should have experience in creating social media graphics and be able to provide a portfolio of their work. The project will involve designing graphics for various social media platforms, including Facebook, Instagram, and Twitter. The designer should also be able to provide guidance on the type of graphics that would work best for each platform. The project will be focused on creating eye-catching promotional material that will help increase engagement and drive traffic to my website & social media account.
