Case for product

I am looking for someone to design a small product case that is suitable for packaging my product. The product is 5 inches and under, so the dimensions of the case need to be tailored to the size of the product. Additionally, the material I would like the case to be made out of is plastic. I need a professional who understands the importance of design and craftsmanship to create the case, and who also understands that the case needs to stand out on shelves when on display. In order to have a successful end product, I need someone who will be available to consult with me and discuss any design details.
