Tim at the Thinkery is a first-class support artist. He'll get back to you right away and put up with you when you have no idea what you're talking about.
And of course, the module they've built is awesome! My client loves it, his real estate clients love it, we've bumped up our Google ranking in 2 months. I highly recommend Tim and his team at the Thinkery.
If you want to have the best real estate site, you need to work with these guys.
