cartoon drawing for women tote bag

Hello,we are designing and eventually producing women's tote bag with a design in mind with cartoon character. The drawings will be embroidered, therefore it is important that the design has black and white drawing but with one or two characters in happy colors. We would like to have simple but yet sophisticated drawings in the design. Nothing of the childish or goofy type please. The target consumer for this bag is quite unique and affluent and it will pricey respectively . Also, I would like for our design to be unique for our product only and not used by any other entity in the market with any other merchandise regardless . Please provide the file that we can convert to embroidery machine. Thank you.
