There are many kinds of elevator sales, I don't know if you want to set up your own company to become an agent of the elevator manufacturer or do you want to do direct sales of the manufacturer? If you have a lot of friends and a lot of people are the development of strength, then many projects do not need you to run, as long as you do the relationship can be, but if you go to run their own projects out of thin air, I'm afraid that no matter whether the customer or the bidding unit will first ask you for your qualifications rather than directly give you the project to start to do, to give you the advice is either in the elevator company within the turn of the sales position to work out for a period of time, naturally, there is a channel, or go to the manufacturers of direct sales. There is a channel, or go to the manufacturer's agent to do sales, accumulate experience, the ability to operate this project may require someone to take you a period of time before you can act independently.
