All-in-One Church Management System for Smaller Churches

I have an idea for a lean software-as-a-service offering for smaller Christian churches, packaged as a whole and priced based on church size. The app would be exclusively web-based, and pretty opinionated, geared toward quick setup and intelligent defaults, to help churches with few staff/volunteers manage things simply, without the complexity of a larger system like Planning Center.

At least initially, the system would include:

- Church website publishing - Sermon library - Event management - Service/Liturgy organization - Hymn/Song management

The idea would be to keep things simple and small wherever possible (team and scope), so that the price point could be low enough for small ministries.

Do you think there's a need for something like this, or is the market already too crowded?
