I need a shirt/hoodie designer

I want to create an ecommerce with shirts, hoodies, mugs etc with professional and unique designs. I will give all the text and a design idea but I would be very happy to find someone who want anytime send me his/her ideas.

At the start I would to test the candidate and pay him/her for a single job, then if we will work together, I will be available to start a collaboration part time or full time as the candidate prefer.
