Is it possible, when a product shows as "out of stock", to hide the price?

This would allow us to set on hand quantities to "0" for the products we want to show for listing purposes only, only changing the phrase "out of stock" to "call for price" in catalog/includes/languages/english/product_info.php. We have a lot of high ticket items which require negotiated pricing.

In our particular circumstances, we do not use our storefront to monitor our inventory levels, so this would seem an easy way to integrate a "call for pricing" mod...

I tried the "call for pricing" mod listed in the add-ons and kept getting errors, so I gave up.

We are working with osCMax v2.0 RC2

Thank you in advance for your help..
