Phone Case Manufacturing

I am in need of a phone case manufacturer to create a small batch of cases for iPhone units. I want the cases to be made of plastic, and the overall quantity should be less than 35. The cases need to be designed comfortably and stylishly in order to meet the needs of my customers. I would like the cases to be light and slim, as well as impact resistant. Finally, I need the phone cases delivered on time and would love to build an ongoing relationship with my manufacturer.
