Looking for a long-term t-shirt graphic designer

I am currently looking for a shirt designer. I own an online shop for clothing. Summer starts soon and so does the sells. I am going to release a ton of designs. That's why I am looking for a new designer who is interested in a long-term job position.

Please provide me with a portfolio of yours so I can check out if I like your past designs.

Greetings

Tuncay
