DNN Event Publishing System

Here's what I need - a DNN (or something comparable) site that has 3 basic functions: 1) List Venues by Category 2) List Entertainers by Category 3) List Events by Day and Category Basically I need for anyone to be able to create an account and enter an event. When entering the event there should be the following options: 1) Title 2) Description (WYSIWYG) 3) Date (recurring or once; start and end) 4) Time (optional - start and end) 4) Image (optional) 5) Venue (optional - choose from list or "add new" function) 6) Entertainer (optional - choose from list or "add new" function) 7) Category 8) Premium Listing? Option (checkbox - redirect to paypal for payment before submitting) Once entered, these events should be sent to an admin for approval before posting. Any events marked premium should show in date order at the top of all other event listings. Also, this all needs to be connected somehow. For example when viewing a venue, you should be able to see any upcoming events there. And when viewing an entertainer, you should be able to see any upcoming events as well. I have a site that this will be patterned after, along with admin access for developer to get ideas. It is www.cajunnightlife.com. Please email any questions. Thanks!
