Employee scheduler for Joomla with community builder

I have a Joomla 1.5 site with Community Builder installed. I need someone to either point me in the right direction here, or do the work themselves. The website is designed for an acting company. Each member of the company has a Community Builder profile. I need to create a way for the Admin (owner of the company) to be able to set a schedule for all the members/employees. Basically, the admin would have a calendar with different shows on it. Then, for each show, the admin can also add members/employees to that event. These members/employees would need to be able to see their own specific schedule when they log into the site. For instance, the admin would create an event on January 1st and January 2nd. Mary is working both, but Joe is only on the 1st. When Mary logs in, she needs to see both events (on her profile or somewhere) with her name listed. Joe would only see one event. All I really need is for the admin to be able to create an employee schedule and have the employee find out when they are working (specifically, not by sharing 1 big calendar). This seems like it should be a common request to me, but I can't find any joomla modules or components that can do this. I'm looking for help finding and implementing one, or a quote on building one from scratch if it doesn't exist. Needs to integrate with CB. Thank you!
