Business idea - creating apps for churches

Since I created the My WDW tips app and later released an ebook on how to create iPhone apps and droid apps without programming at www.unbeatableappdevelopment.com, things have slowly started to unfold.

I had an idea to present to large churches that I can develop an iPhone or droid app for their church. An app for a church would, I think, be a perfect fit for some churches, and could do things like keep schedules and announcements updated, link to sermon podcasts or notes, give a bio on the staff with contact info, directions, Sunday school class listings, and a host if other things.

I think this may be a great niche for me, and my development partners agree, and would create one app as a showcase and reference app at a reduced cost.

What do you think about this idea?
