There is no better way to learn than at the exhibitions you participate. How does the truss system blend in with the business and how does it enhance the effectiveness of the salesmen? For example, how do you put a 10' trade show exhibits to good use? Look at what some of the exhibitors are doing with their 10' trade show exhibits.

Ensure that your business gets the attention that it deserves with the use of truss systems. Truss systems are a good way for exposure, and to a lot of people at once. Still, you don't have to limit yourself to exhibitions. You can be the sole exhibitor. For example, you may want to set up your truss system and get some publicity for your products or services at a car-park, shopping mall, etc.
The fact that you can use a truss system as many times as you need makes it even more viable to have your own truss system. Once you have your own truss system, you only need to make arrangements for where and when to set it up and with how many of your salesmen to be in charge of. You can create even more revenue for your company with the flexibility of owning your own truss system. You already have your salesmen, you just need a sales boost for your products or services, unless of course, you are already overloaded with orders and your salesmen are too busy with on-going work. But then, all this is a matter of arrangement. If sales are not as good as expected, you should certainly reevaluate and rearrange.
