I came from a similar background so thought I would reply. The way I learned was by watching those who are good at it, tagging along and assisting where I could, then striking out on my own. If you have a little extra money for a commission on early sales, I would highly recommend this approach. There is a lot to be said for seeing someone work under the specific set of conditions your product and domain entail. The biggest piece of general advice I have is to set aside some time before sales meetings to fully get your head out of the technical details of your product. When you're making the product your mind is focused on what the product is and all its faults and inadequacies. Your customers need you focused on what their problems are, and the capacity your product has to solve them. You may need serious wall clock time, maybe a couple hours, to transition completely. Remember why you made this thing, remember what the world looks like without it, that's where your customers are and you need to understand their point of view.
