I second Athanasia's advice on checking what, if any, is the "going rate" (horrible terminology, I know) at your church. Of course, this doesn't stop you from contributing more than the accepted amount if you wish. I was recently at a church (not the one I attend) where our church's choir was invited to sing at a wedding. At the end of the service, the priest paid our choirmistress the "going rate", and added another hundred on top, because they did such a good job, in his opinion.
