designer for a print of demand business

I am looking for a talented designer to create more than 10 different t-shirt designs for my print-on-demand business. I already have a specific concept in mind, and I am looking for someone to bring this vision to life. The designer should have experience creating stunning t-shirt designs, including logos, typography, and illustrations. Ideally, I would also like the designer to be able to provide guidance and suggest creative solutions to improve the design as the project progresses. If you have experience in t-shirt design and think you have the skills necessary to make my vision a reality, I would love to hear from you. If you have your own disigns you can show them to me too.
I am also looking for designs about Halloween.
All the designs I'm showing are just examples. models to follow to offer a more complete idea of what I want.
