Magento Admin Permissions

Looking for a Magento programmer to add the ability to assign 1 or more attribute sets to? *admin*? users so they will only be able to add and edit products under a specific attribute set. And of course, when adding a new product they should not even see the other attribute sets available. You must have completed a custom Magento project in order for you bid to be considered.? Please have in mind that I'm a web designer, and there might be a long relationship, if you turn out to do great work in a timely manner.
