Church website with minor custom content management system

I need a website designed for a church. The site would need to have a clean and custom design. If this works well I would like to form an ongoing relationship, sending about 1-2 new projects every week. Most importantly I would need it to feature a minor CMS system What I mean by minor is that select users, upon logging in, would be able to submit calander changes, events, and articles. These submissions would be reviewed and approved by an admin who would then publish those changes to the site. You would not have to write or fill in copy - I will do that. Site would need to feature the following: * Custom Look and Feel * Interactive Calendar w/ important dates. Calendar can be changed by approved users and approved by a super user * Group level access to certain pages (rights control) * Google maps directions to the church (on contact page) Please send examples of similar work to be considered. You will NOT be considered without examples.
