design business card and logo

I'm looking to create a business card and logo design that accurately reflects my business and aligns with my goals. Since I'm not sure what size I would prefer, I'd like to leave that part open to the freelancer to suggest the size which best enhances the design. When it comes to logo design, I'm open to either a rectangular, circular, or square design. As for colors, I'm looking for a combination of neutrals, bold colors, and pastels, so I am hoping to see suggestions of complementary colors.
