Can I make stop backorders of one-of-a-kind items once sold out?

Here's my store

OK so I have alot of One of a Kind Jewelry and I need to remove the backorder option from these items if they are purchased.

Also once they are purchased is there a way to keep them in the catalog but only veiwable in the admin section?

Hopefully this will be my last question.

Hi there
When I have only one of an item as clearance stock I set on hand qty to 1 and max order qty 1. This now ensures that this item will only be sold once. And in addition if you wish you can also set:
Products Quantity Box Shows: No, this means the customer can only add the default qty of one to their shopping cart. If two customers add an item to their cart at the same time then however checks out first will get it.
