Make raises one hundred percent commission based, but give everyone a stake in finding new business. Even accounting and IT teams can find clients, so create an upside for them, too. When everyone in your company has a stake in the outcome and can make more money by bringing in clients or employees, they will work to help you build your business.
Also, teach your employees how to network. Give them marketing pieces with a promo code customizable to that employee. Help them make more money and you will too.
