product design for seat cover

I am looking for a talented freelancer to create a custom design for a seat cover to be used after a workout to protect the drivers and passenger seats in an automobile. I have preferences in mind for the colors and materials to be used in the design but am open to suggestions. I'm looking for a seat cover that will provide a stylish, customized look for my car while also protecting the interior upholstery from sweat. I have an exact look in mind, just need someone to build out the specs so I can have prototype built.
