I need an iPhone/iPad app. I would like it designed and built. I'm looking to create an app for Apple and Android the local religious community, which features a discussion forum, events page (that can be synced with outlook) and weekly messages that can be pushed out. Also, a platform to store / link weekly videos and send weekly alerts onto people. We'd also need a place for people to vote on polls. We expect around 1000 people to use the app.
Please let me know how much something like this would cost to make /maintain and what timescales you'd be looking at.
