$50 USD -- OSClass Plugin -- Custom Products attributes USA Theme

I need a plugin that allows me to specify custom attributes in the OSClass Admin Panel. These attributes need to update the search field with a drop in box that lists all attributes I specify. For example; Say I create custom attribute Hair Color with the following fields > Black, Brown, Blonde, Red. The field hair color must show up on search with a drop down encompassing each field. It must work with the USA theme. This must be made as a plugin to OSClass standards. [login to view URL] The plugin will be released back to the community. Budget is $50 maximum.
