I can't speak for sales/marketing, as we employ zero. But if you've opted to employ a sales team and they're not landing clients, it's likely them that's your problem.

Our contracts are literally all self-referred or reputation-referred. My partner and I each have multiple long-term clients, some of whom are former fulltime employers.

On that latter point, a very common method is to "quit" your employer and then they immediately retain you as your anchor client before you begin the process of shopping for more.
