Put my designs on a t-shirt images for my website

I need a graphic illustrator, who can take my design illustration and place it on t-shirt images and hoodies.
The images are to upload to a fashion website, It has to be done to perfection, the right colours, no blurred images.
I'm looking for someone I can work with on a regular basis. I want 10 images, five on black t-shirts and five on white.
I have the design already, its just to place it on the t-shirt image.
