A couple of weeks ago I came up with a service for offline businesses, basically offering targetet traffic for their social media. Long story short, I've only contacted one person (thorugh facebook) and we have now booked a meeting for tomorrow. The problem is that I do not know what we should talk about. I have already explained what the service is and how it works. Should I just repeat what has already been said? Should I prepare some graphics? I am not a great talker so I can't just keep conversing like it's nothing. I should probably add that I am only 17 years old so I might come of as too young. I have zero experience with dealing with any business and have zero references. Any advice would be appriciated!
