Here's the reply I got from them:
"Presently, we do not accept only 14 day Free trial hosting orders as we have some problems with the automatic installer tool which we are working to fix it soon.
We accept all paid orders and setup the orders manually. "
I would recommend anyone seeking shared DNN hosting to try Websecurestores. I have used them for 1.5 years and every support request I had was answered quickly. My sites have been blazingly fast and are rarely down. When they are down it's 5 minutes for an IIS restart. They are also good about notifying customers of planned outages.
The level of service you get with a simple $10 account is amazing.
