It seems like several members have had trouble with this company, including one of my own clients.
In general, I advise you to be very weary of marketing agencies that claim they can get you huge coverage and easily fund your campaign. Some agencies really do have media connections and can be a great source of advice and media attention, but I would recommend focusing on your product and your story first. If you feel like you have something really newsworthy, consult an agency.

Check out these things first, if you feel like you need extra help, at least you will have some good background information to tell the agency that you speak with.
Hope this helps a bit =)
