Need someone to create streetwear concepts for our brand

Hello, I'm looking for someone to create some streetwear hoodie concepts for my brand. I'm aiming for a minimalist style and I'm open to any colors or patterns. I would like at least four different concepts created for this project.
Im looking to pay $20 per concept. Im looking for someone long term.
If you have experience in streetwear fashion or design, I'd love to hear from you!
