I tried to reach them unsuccessfully for about three weeks before I gave up a couple of weeks ago. I ended up going with carts from Vendog (located here in SC), but had trouble reaching them as well until a fellow Roadfooder gave me the owner's cell phone number. I suspect that for most cart builders it is simply the busiest part of their season. FWIW, I really like the Island Time carts on the site and the one I looked at locally. They seem to be high quality products. Good luck in tracking them down. I know sometimes it seems counterintuitive to have to hunt someone down to give them money!
One very effective way to get their attention is to call one of their neighbors and ask them to take a message over to them. I imagine it would be embarassing for a business to have a neighboring business come to you and let you know that a potential customer is trying to get in touch with them but can't.
