I want to set up categories that are only visible to customers who are listed in a specific Zen Cart group. No one else can access these categories nor should they be visible to any user other than those in a Zen Cart specific group. Once accessed these unique categories need to function as normal categories as in the add to cart function.
All work should be thoroughly tested and working on Zen Cart ver1.3.9h. If core files are to be modified, the code must integrate into existing core files that may or may not have been altered from previous addons. Detailed integration instructions and integration assistance to existing files must be provided. Current site core files will be provided.
Must have excellent English both written and spoken. This is an immediate need.
