Camera to stream church service

[Marshall]

Small church with idea to stream video and sound of it's service on Sunday for shut ins and regulars who can't be at church that Sunday. Can someone aim me to information on what it takes to do that? Our webmaster says we're okay on his end if we can camera to PC on wireless. Need to shoot from 100' away and mike the music at that camera location but could probably mike the pastor on a wireless.

Any suggestions?
