There are so many places to find chord charts. Here are the 5 places that I go on a regular basis to find song that I am looking for.
www.iwillworship.com
www.praisecharts.com
www.worshiparchive.com
www.christianguitar.org
www.pwworship.com
Many of these are in the keys the songs were recorded in in, which means you might need to transpose up or down depending on your vocal team. There are a few places that allow you to copy and paste chord charts and transpose them immediately online. The ones that I have used are listed below:
