CRE loaded Modifications

Hello, I am looking for a php coder that is proficient in CRE loaded / OS Commerce. The actual product is CRE Loaded B2B v6.2.13 (SP1). What I need is someone who can alter the code so that the “buy button” / “add to cart ” button for products can either be disabled or enabled. What I mean by this is when a product is added, I want to have the option to tick a box to disable or enable the buy button. However, all the products can still be added to the “wish list”. It should also be noted that when a product is in the wish list the “move to cart” is also not present for products that have had the buy button disabled. This is a simple project for someone that does this type of work. Files and more information will be provided to the successful bidder. I am looking to pay between $30 and $250. I would like to get started on this ASAP. Thanks,
