At this point, the sky's the limit, but don't try to do too much. The downfall of many productions is attempting to incorporate too many elements and having issues that jeopardize the production.
Try adding elements one at a time catering to the needs of the broadcast. Some productions would benefit from more camera angles, some with better graphics or with better audio. Be sure to test your equipment before you use it in a real production setting.
Be creative with your productions. Start planning productions days in advance creating a rundown and outline of the action.
Begin setting a reliable crew who know all the intricacies of their jobs and are able to teach other people.
Watch professional productions and use their ideas in your own broadcasts. Pay attention to camera angles, graphics and prerecorded content.
Beyond everything, STAY ORGANIZED. Nothing is more frustrating than needing to find something or someone and not being able to because you're disorganized. Keep spreadsheets or organize crew and equipment. Create shared folders such as a Google Drive or Dropbox to compile content.
Finally, stay in communication with your whole crew to ensure a streamline clean broadcast where everyone is working together to create something awesome.
