Simple designs (many) for print on demand with listings optimation and SEO

I am looking for a designer to create multiple mug designs for my print on demand business. I am open to the designer's creativity and do not have specific themes or ideas in mind. The ideal candidate should have experience in creating eye-catching designs that are suitable for printing on mugs. Additionally, the designs should be optimized for listings on etsy, print on demand platforms and have good SEO . The project needs to be completed within a week.
