First of all, there is no such thing as a 100% hit rate in sales. So you can forget about your presentation convincing 100% of buyers. That’s called being naive. Secondly, as I see many people here offering their own services, I’ll ask, why do you think someone else is better at communicating YOUR value proposition to YOUR customer-base than you are? If you need help with the visuals, I get it, but it’s your prospect, your product, your value proposition. You can’t outsource that.
