Answer the questions clearly and concisely and then always re-phrase your response as a question back to the prospect to get a positive answer from them.
When you complete your presentation always REVIEW the things that you discovered are important to your prospect in a statement and then ASK how they would like to get started. If you have several "packages" then ALWAYS give them a choice so they can select one.
The Magic and Success of ANY presentation is one that allows the prospect to feel you are genuinely interested in them, have a solution to their challenges or needs, and are the type of caring and capable person that can help THEM achieve their goals and dreams.
