Create graphic designs for t-shirts and hoodies

I need someone to create graphic designs for t-shirts and hoodies. To begin with, I want to start with classic US States designs (examples included). I am looking to start with 10 designs but in the long run, I will need 500 -1000 designs for this project. It is best if the designs are simple and classic. All designs must be original, but I will send you a list of designs to base your work on. My goal is to find an artist who I can rely on and work with consistently in the future for larger projects. Please let me know if you have any questions.
