Your company doesn't train/? First of all, you should know the business scope of your company and the basic information of each item, so that you can push it. Practice makes perfect. If you talk more, you will naturally know how to organize and promote the language. I don't know what model your company is. If you are looking for customers, the more customers you find, the greater the probability of quality customers. If others are interested in doing this, they will naturally give you contact information.
