Plugin Recommendation or Developer Request

I need to be able to do two things. I need a calendar that members can sign up for a specific date that allows three listings per day. I also need a form that automatically generates the entries into automatic blog posts. Even better if the calendar and form are integrated. But I’m fine with two separate plugins if they do these two things. Any suggestion on what’s already available would be appreciated. I’ve combed through the plugins and can’t quite find what I’m looking for.
