Where can i find a cell phone case?

I need a cell phone that i can design myself... but i DO NOT want one of those skins.. like skinits.. or whatever, i want a hard clip on one! and it needs to be able to come off and be put on again... cause those skins can be only put on once. i need it to protect my phone!Where can i find a cell phone case?
