I took a look. Quite honestly, I'd stay away from them.
Agents and their agencies have contacts in the publishing industry, they're professional and know their business. It's how they earn their living.
I was once caught up with an agent who sent out blanket emails to publishers, or so the agent said. I was never able to get a list of submissions, and there was never a response from a publisher. On the thread where I mentioned that, someone who works for a publisher advised that they ignored blanket mails from unknown agents. I feel that the service provided by publishersand agents would fall into the same category. You're better going it alone.
