I need a designer to provide a bulk of ideas and pictures for tshirt & sweatshirt printing images

I have a textile shop, where I can produce printed t-shirts & sweatshirts. I am planning to have different types of simple designs to use on that material. There is no limitation however basic simple designs around 100 different types of images would have been great. I would be happy to discuss it around. Not a complex job, but requires a decent effort.
