custom t shirt design for POD

I am looking for a custom t-shirt design for my POD business. The designs should be unique and something that will stand out. I need someone who can create an original design for the t-shirt showing off my brand - it should be eye-catching, stylish and unique. The design should be text-based, logo-based or complex artwork, whichever is most suitable and creative. I do not have the artwork ready, so I need some assistance in coming up with the design. Finally, the t-shirt will be printed on cotton fabric, as this is most suitable for the design.

We need 25 designs for this first step, please send us your previous work.
