Show part of collection in Catalog mode

[Rutger]

Hi,

I'm looking for a module or solution which gives me the possibily to show a part of the collection without the add to cart button. A part of the collection should be available to purchase. 
Setting stock to 0 is not the solution for me because we have an automated stock update every hour or so. So even if we have stock we do not like to sell the items online but as brand website I feel the obligation to show the entire collection.

In the product catalog in backend I found I can set a product as not for sale but with this function the button still shows on PDP.

Thanks
Rutger
