Individual Schedules for Users

I am creating a website for a personal trainer and he wants to be able to create workout schedules for his clients and then have them posted on their profile pages. I am trying to get that done with an event style plugin and though perhaps this would work? Or any other suggestions. I found CF whiteboard as well as WP Wod and they are a little out of the price range considering that there will only be a few clients using the site at a time. Any suggestions would be awesome.
