Design some Icons

I've created a electronic lockers application where a user can hire a locker to store their valuables if they go to a water park for example. I'm after two icons that show "New Hire Locker" and "Open existing Locker" -> "New Hire" picture : a simple pic of a locker with the door open and nothing inside. -> "Open Existing Locker" : a simple icon of a locker with the door open and things inside like a suitcase and wallet for example. I'm after two icons that clearly depict what I've described above. No text is needed on the pictures. I've attached two pictures that show what I'm doing. I don't like the red colour as it is too bright. It's just an example of what I'm after. I'm open to ideas. It doesn't have to be 3D - it can be 2D drawings as well. regards, Adrian
