Welcome Tim! You are in the midst of quite an adventure! It would probably be a good time to do a SWOT analysis so you can build strength and avoid future burnout and other issues.
SWOT is Strengths, Weaknesses, Opportunities and Threats. Make a column for each, and write brief notes about anything you think fits in each column pertaining to media ministry. Work on that for a while, put it down and come back to it a couple of times.
When you think you have all four components covered, ask God for vision on how to deal with the weaknesses and threats, and how to leverage and grow the strengths and opportunities. Then you can begin to put together a strategic plan to present with your pastor. Make sure it remains in alignment with vision and mission for the church.
Let us know how things are going, and welcome again!
