If you plan to do any short, low-production, or live video from your phone, this amazon basics phone Tri-pod would be a great tool for you:
Selfie Stick Tripod, UBeesize 51″ Extendable Tripod Stand with Bluetooth Remote for iPhone & Android Phone, Heavy Duty Aluminum, Lightweight
Also, the app iMovie is a simple video editor on your iPhone that you can use to chop up short, prerecorded announcement videos.
There is also still room for higher quality videos filmed on the church video equipment that I can assist with, otherwise I am just a phone call away if you need help with editing in iMovie or have a question about live streaming.
