There was a time when the common medium-sized (or larger) Southern Baptist communities had single ministries that were fairly successful.
Lately though, a lot of them have been scaling back on them. The reason is because (A) they're trying to appeal to certain types of married families (because those they have lots of babies) and (B) Millennials and younger Gen X'ers are taking a lot longer to get married for different reasons.
So my point is that you might have a real challenge on your hands.
