Custom made macbook pro 13 in cases?

I have been looking everywhere for a case that is a little bit different than all the others but is still protective. I looked at my phone and saw my otter box commuter series case.So I thought that case for my macbook pro would be great. Obviously I can't find it anywhere. So if someone knows where to get one or a place that makes custom cases please let me know. Also why don't they make cases like this?
