Seeking some used live streaming equipment

Hello to all,
I'm getting our Parish into LiveStreaming content on YouTube, and I'm looking to acquire (purchase/trade/beg/etc) a better camera than my phone, and some other streaming equipment that I can dedicate to the task.
Even any advice on models from people with the AV/IT experience that I'm now learning will be of great help.
Thank in advance for any help, advice, tips on equipment or anything that will help me to make our LiveStreams a more professional looking thing.
