I am the pastor of a smaller congregation in a rural area. We have an organist who is very faithful in her service, but every once in a while asks for a Sunday off. While many of the congregations around have someone who would be willing to fill in for their own congregation in a pinch, nearly all are not comfortable enough to play for another congregation.
We would find it helpful (and possibly a gateway to finding broader use and thus purchasing a full license) if there were a way to use Concordia Organist on a pay per use basis for those occasional and rare situations where our organist is unavailable.
I really have no idea how complicated it might be to set something like that up. Perhaps it would be easier to do a 30 day trial membership for $30-$50 or so?
