Where can i get 3D custom silicone rubber Iphone cases made?

I have been looking into getting custom rubber cases done for my team. but i don't know where to start. I have found a few factories in china but the translation is off and I rather be able to specifically communicate with them about the initial sample.

It seems as if all these products are made in China but i know their has to be some company's in the US that can make custom silicon cases.

Were you trying to just get a regular case with some design on the back?

If so just Google custom cases and you'll find a lot.

Nah i need it to be fully 3D and silicone most of those places offer small customization
