I'm a CRC planter in Manhattan, NY.
I just wanted to pass along a recommendation for a website that we've found very useful here in NYC that is now going national.
Its called Faith Street (faithstreet.com). I'd encourage you to explore the site and see if it might work well for your context.
In short, it helps people find your church. Churches create profiles and people who are new to the city or new to faith begin their search at Faith Street. Recently, they've even started matching people up with some of their preferences (e.g. I get a lot of people who are looking for a Reformed/Presbyterian church in downtown Manhattan).
Check it out, let me know what you think and keep an eye on it for when it launches in your area. Its really been a great thing for Dwell Church!
