Sketch Based Designs for brand merchandise

I'm looking for an experienced freelancer to create unique and eye-catching sketch-based designs for my brand merchandise. I'm specifically looking for designs in the form of sketch art to be used primarily for business logos. Depending on the project I have in mind, I will require the freelancer to create more than 7 of these designs. To be clear, I'm not looking for photography, digital paintings, designs for print ads, or product packaging. This project should make use of a freelancer's creative skills to help create something truly engaging. The right outcome will become part of my business brand identity, so quality and attention to detail is of utmost importance.
