I need a CAD drawing of my idea

I have an idea for a plastic injection mold product but I need a CAD drawing to be able to take it to the next step in the process. It is a device that would attach to an iphone lightning port. It would have an integrated lightning port with a male and female lightning port enveloped in plastic with a scoop that would surround the speaker port of the iphone. I don't have a drawing of it but can provide one if necessary. I need a quote for the CAD drawing and a 3-d rendering if possible.
