Hi EW,
If they have never read your book, then YES, BEWARE! After a little research, it seems that the founder of that publishing company also owns Strategic Book Marketing:
http://www.strategicbookmarketing.com/

This markeing company offers many marketing services that I'm sure they will expect you to buy if they publish your book.

While it never hurts to call them and chat, have your guard up and back away if they ask for any money or financial committment.

Here's a link to a discussion about them:

My 2 cents...
