You can use LinkedIn to post your job to the more than 50 print-related sites out there. You can use Facebook and Twitter. You can network any way you can. You can go to the mall, and if you find a particularly talented salesperson at Macy’s, offer to take him/her for coffee to see if s/he could make the transition to outside sales. (That’s where I came from...well, not Macy’s but retail.) But if you keep doing what you’re doing, you’ll keep getting what you’re getting.
Your salespeople are underperforming. Many great owners of great printing companies will admit that they are not the best managers of salespeople. They lack coaching skills. Encouragement is not their strong suit. When they talk to their salespeople, all they can think of to say is, “Go SELL something!!”
There is a vast amount of resources out there to help your salespeople succeed. Why, this very writer offers a Webinar series on improving sales skills and hot markets (apology for the self serving comment). But seriously, no matter what your budget is, you can find a way to help your salespeople become better at what they do. Look around. Not only will the investment benefit you, but it will tell your salespeople that you care about their performance and are willing to do what it takes to make them better.
You are considering transitioning to new technology or getting into a new market. This is an instance where I would lean very heavily on an outside vendor (maybe more than one), or I would even consider talking with a consultant who can be more neutral.
Whether you want to get into digital, large-format or variable data printing, any vendor worth its salt should be able to come and talk with you, help you think through your plan—what you want to accomplish, what resources you have—and make recommendations. If they cannot or will not, or you don’t trust what they are telling you, keep looking. Or ask a friendly competitor. Or get online and do the old networking thing. Or come ask me.
