Do you have an internal marketing team? How about an internal sales and marketing team? Is your "team" or "committee" 1 person?
If you don't have anyone in-house that's working on marketing your business, you're not alone. I'm always astonished at the number of decent sized companies that we work with that don't have a dedicated staff for marketing. When a company doesn't put thought into the nuts and bolts of how they get new clients, who they are, and how to best reach them, it creates a challenge for companies like ours.
