How to sell?
skmurphy: Focus on asking the right questions and then giving good answers (this may often involve follow up in a second conversation). Work as part of a sales team so that the presentation burden can be shared. Develop and maintain an extensive FAQ for your product so that others can also speak knowledgeably about it. In the end introverts can make excellent sales people because they are willing to listen and give thoughtful responses. Most of the time you are "selling with your ears" so help your team succeed. SPIN Selling by Neal Rackham is a good intro book on sales.
