Rommeldawg, I think staying with them is probably a mistake.
If a working agent there can't name any of their clients whose work they've sold, that's a gigantic red flag emblazoned "RUN! RUN FAST!"
Will they cheat you? Maybe, maybe not. Are you likely to be the very first author whose book they've sold. No.
The second message in this thread, from Victoria Strauss, tells you that they're not a good agency to go with.
I hate to be the one to say it bluntly, but after sending out queries for two years and getting no bites but this one, it's probable that either the query or the novel is not what it should be in order to land you a 'real' agent.
Maryn, sorry to bear bad tidings
